Abstract:
In this paper,optimization researches were conducted on the SSR reaction program and the reaction system for the research process of Q. liaotungensis genetic diversity. The optimized reaction program was to adopt 33 cycles,which included 3 minutes of pre-denaturing at 94℃,45 seconds of denaturing at 94℃,45 seconds of annealing at 58℃,45 seconds of extension at 72℃,and a final extension step was carried out at 72℃ for 7 minutes. The optimized reaction system was as follows:30 ng DNA,2 μL10×Buffer(Mg2+ Plus),150 μmol·L-1 dNTP Mixture,0.3 μmol·L-1of each primer,1U(5 u·μL-1) Taq polymerase,and the total reaction volume was 20 μL. The results had a certain reference value for the application of the SSR marker in the research on the genetic diversity of oak plants.

Abstract:
Light-response characteristics of an introduced tree species (Nyssa aquatic) under the environment of high temperature (35℃) in Three Gorges Reservoir Region was measured by using a Li-6400 portable photosynthesis system in August of 2012. The results showed that net photosynthetic rate,transpiration rate,stomatal conductance and CO2 use efficiency of Nyssa aquatic increased firstly,then a little slowed down with photosynthetic active radiation increasing,but light use efficiency decreased with photosynthetic active radiation increasing; The maximum net photosynthetic rate was 6.587 μmol/(m2·s) and the view of the quantum efficiency was 0.077 mol/mol; Its light compensation point and light saturation point were 16.69 μmol/(m2·s) and 481.82 μmol/(m2·s) respectively. It indicated that Nyssa aquatic had a stronger adaptation for the environment of high temperature in summer in Three Gorges Reservoir Region,and had stronger shade tolerance, so Nyssa aquatic introduced could better adapt for the ecological environment of Three Gorges Reservoir Region.

Abstract:
Based on the field investigation and soil analysis,studies were made of effects of intercropping on the growth,soil nutrients and benefit of young Camellia oleifera forest. The main research results were as follows:by intercropping with soybean,eggplant and chili in young C.oleifera forest,the survival rate of afforestation and benefit of young C.oleifera forest increased,but the effects of different intercropping on soil nutrient were different. According to nutrient requirement of C.oleifera sapling plants and crops,intercropping soybean should be appropriate to employ potash and phosphate fertilizers,intercropping eggplant should be appropriate to employ nitrogen and potash fertilizers. Intercropping in C.oleifera afforestation was feasible,but according to local conditions,reasonable intercropping was a necessary prerequisite to achieve the desired effect.

Abstract:
In recent years,a series of restoration and control experiments have been conducted on slightly degraded sanded land and fixed and semi-fixed sanded land in Zoigê County,and some suitable modes have been put forward for slightly and moderately sanded land. It was also found that (1) the survival rate of cutting willow was obviously reduced in sanded land. (2) Willows whose diameter were equal or greater than 1.0 cm had a higher survival rate.

Abstract:
The high-efficient cross-infection seedling-raising technique of truffles were proposed firstly in this papor. The hazel and pine seeds were inoculated in the tub containing the water-retaining agent adsorbing the suspension of truffle spore. After five months, the mycorrihzal seedlings of truffles were transplanted. 3 000 mycorrhizal seedlings were produced by using only 200g of truffle ascocarp. This technique would be very useful in the cultivation of mycorrihzal seedlings.

Abstract:
A pot experiment was conducted to study the physiological responses of Pilea cadierei Gagnep. et Guill to single cadmium(Cd) or lead(Pb), and their combined treatment. The results showed that the activities of SOD in leaves would increase with the concentration increasing of single Cd and Pb. When P. cadierei was treated with combined Cd and Pb, the activities of SOD would decrease. The activities of POD increased in the use of lower Pb concentration but decreased in the use of higher Pb concentration. It was indicated that Pilea cadierei had definite Pb-tolerance capability in the use of lower Pb concentration but was damaged in the use of higher Pb concentration. In the use of combined treatments of Cd and Pb, the activities of POD would gradually decrease. That further confirmed that the combined treatment had a higher toxcicity than single Cd or Pb treatment. The contents of Pro and MDA all would gradually increase with the concentration increasing of single or combined Cd and Pb, which was a physiological adaptation of plants to heavy metal stress.

Abstract:
Nowadays,domestic zoos and wildlife protection agencies put more and more attention to the protection of investment in education. However,in order to protect and guarantee of the sustainable development of the educational projects,the profit is also an important issue which policymakers need to take into consideration. The number of tourists is fluctuated by several factors,for example,the salary level of tourists,the convenience to reach the zoo,and the hardware environment to improve the extent and valueadded services. The main aim of this paper is to discuss whether carrying out wildlife conservation education will increase the number of tourists or not. From 2006 to 2011,Chengdu Zoo already carried out various forms of conservation education project. Based on the analysis of the relationships of the number of conservation education projects,the number of people involved in the activity and the amount of zoo visitors,it could be preliminarily concluded that there was a positive correlation of the investment of conservation education project with the number of tourists.

Abstract:
In this paper,studies were made of the establishment of above-ground and below-ground singletree biomass equations of aspen. Firstly the work was done for establishing its total above-ground,stem wood,stem bark,branch,leaf independent biomass models and compatible models with the volume biomass. Then a system of aspen biomass models was established,in which the total above-ground biomass equations were compatible with stem wood,stem bark,branch,leaf biomass equations. Finally a root-shoot ratio model was established,which could be used to estimate below-ground biomass together with aboveground biomass equation. The results showed that all the models should be able to fulfill technical regulations and to be applied to the biomass estimation of aspen.

Abstract:
Sichuan has rich eco-tourism resources. Its forest parks are an important carrier for the development of ecological tourism and ecological civilization construction. After 20 years of development,the forest parks have formed the models of resource shares,government leading and interest chain effect in the management process. This paper deals mainly with the different characteristics of Sichuan forest park management modes and existing problems. In order to revitalize the forest landscape resource assets,the forest park's ownership,administration rights and management rights can be reasonably separated,aiming to establish the forest park management system and operational mechanism in line with local economic development. Besides,some strategies and suggestions are put forwart from the aspects of laws and regulations and capital investment.

Abstract:
Traditional forest protection work is directed toward the control of the plant diseases and insect pests while current forest protection concepts begin to focus on the function of forest self-repair and forest health. If more attention is paid on the non-control methods and use of the self-repair and self-renew function of the forest ecological system,and full use is made of all the biological resource of the forest system and the unique ecological environment of the plateau,forest protection and cological protection can get more economic support so that many ecological crises can be dissolved before they change into disasters.

Discussion is made of problems and strategies in the implementation of the forestry carbon sink project in Guangyuan City after carrying out the field investigation of the first forestry carbon sink project of Sichuan Province-the project of forestation and reforestation on degraded land of Northwestern Sichuan in China that is jointly developed by Qingchuan County etc. and to the 133.33 hm2 national pilot forestation for carbon sink in Fenshui Village and Jindong Village,Dachao Township Lizhou District Guangyuan City,hearing opinions of persons in charge of municipal and district forestry bureau and bureau of parks and woods,village forestry station and professional cooperative organization as well as reviewing relevant domestic and foreign materials. The achievement is remarkable,but there are also quite a few problems. The forestry CDM project is hard to achieve economical benefit. The sense of carbon sink forestry has to be strengthened and the recognition is chaotic. There are also individual leaders or experts,who make irresponsible remarks or have inconsistent understanding,or simply consider that the fostered forest must be sold out or it must be forestation and reforestation project,or they can not distinguish carbon sink forestation with forestation of the common sense. Or they have vague recognition to the relationship between multifunction and multi-benefit of forest and carbon sink benefit, confuse forest's carbon storage with carbon sequestration,view carbon cycle statically and in isolation,simply consider that the carbon is released after the forest is felled,so carbon is irrelevant to forest. Relevant international and domestic systems need to be perfected. The low carbon research involves not only natural science,but also social science such as ecology,economics and science of law. It is also closely related to rights and interests of relevant international and domestic bodies. The benefit of new carbon sink forest has yet to be revealed. Guangyuan is an underdeveloped region,the risk of early cost of CDM is large and some issues have to be further researched and promoted,e. g.
