Abstract:
China is the most abundant in the resources of bamboo. However,the phenomenon of continuous bamboo flowering and death has caused a heated discussion on factors to restrict the growth of bamboo among scholars in recent years. After collecting and analysing lots of literatures at home and abroad it is concluded that among these factors soil can not be ignored. This paper deals with the current status of soil and bamboo on the basis of previous studies,mainly include studies on the effects of different soil conditions on the bamboo rhizome、shoots、growth、flowering and senescence,and the community density and management models also produce an retroaction on soil. At last,this paper also describes the research progress of the giant panda's staple bamboo in this field,and puts forward an suggestion of increasing the experiment argumentation and the study of mechanism in the future.

Abstract:
There is an ecological relation between predators and prey species,and prey species are often able to detect predators by using olfactory cues. Odours of predators can cause the prey to produce the responses of behaviour freezing,avoidance or defensiveness. This paper deals with the influence of predators odours on the behavior and physiology of the prey species and practical applications in programs of letting animals return to nature.

Abstract:
The study was conducted to estimate the pollen viability of four genotypes and storage conditions. Pollen grains were stored in four storage temperatures and their viability was assessed by in vitro germination. The results showed that the ability of four genotypes germination in dry conditions was better than in others,and the duration of storage was longer as the temperature decrease. With the storage time increasing,the germination rate of lily pollen gradually decreased,but had a distinct rise in some periods of storage process.

Abstract:
In this study,Populus schneideri var. tibetica's stems with buds were selected as explants. A series of tests were conducted on disinfection and sterilization,the induction of adventitious buds,the proliferation of regeneration buds,strong regenerated seedlings,rooting and transplantation in order to study the best training methods during the tissue culture process,and to screen out medium components for plant differentiation and rooting. The results showed that 45 seconds of alcohol disinfection and 8 minutes of mercuric chloride sterilization worked best. The bud induction rate of explants reached 79% in MS + NAA 0.05 + 6-BA 2.0 medium,and the axillary bud sprouted after 10 days. The proliferation coefficient was up to 5.8 in MS + NAA 0.1 + 6-BA 2.0 medium,displaying the best effects. The effect of promoting rooting was significant in 1/2 MS + NAA 0.5 medium after strengthening the regenerated seedlings in MS + NAA 0.1 + 6-BA 0.5 medium. This would provide technical reserve for the cultivation speed acceleration and genetic improvement of Populus schneideri var. tibetica.

Abstract:
Understorey planting is a more promising development enjoying the dual,ecological and economic advantage of agro-forestry economic model. To study the impact of pear + konjack forest planting patterns on understorey soil nutrients,the soil under two kinds of pears (Pyrus and Changji pears) forest was measured. The results showed that the total calcium(TCa) content had a significant increase in the of konjack + pear forest cultivation,but this cultivation model had no significant effect on the rest of the soil nutrients; konjack + pear planting model significantly increased available phosphorus (AP) and total potassium (TK) content in Changji pear forest soil,and yet its TCa content significantly reduced. It could be seen that understorey planting konjack in pear forest had a role in promoting the improvement of the forest soil in a way,and konjack also could bring some economic benefits. Therefore,understorey planting konjack in pear forest was a viable cropping pattern.

Abstract:
In this article, analysis was made of soil samples collected from 7 829.84 hectares of arable land and forest land representing 34 towns of Yanyuan County, Xichang City, Sichuan Province, and research was made on the content of available boron and molybdenum and their influence factors. The results indicated that the available molybdenum contents displayed a skewed distribution. The average contents of boron and molybdenum were 0.3196 mg·kg-1 and 0.1896 mg·kg-1,respectively. The available boron content was lower, and thus the crops were potential boron deficiency. The average molybdenum content was moderate,able to meet the needs of crop growing. The contents of available boron and molybdenum were affected by soil parent material, the cropping system and soil types. In the analysis process, it was found that this area was still relatively lacking in available boron though a certain amount of microelement fertilizers had been used. So the supplement of boron fertilizer was necessary during the production.

Abstract:
Dendroctonus armandi is a destructive insect of Pinus armandi, and causes a serious economic loss to the forest industry in China every year. Determination of the potential geographical distribution of Dendroctonus armandi is an important factor for effectively controlling the spreading of this pest. In this study, niche model MaxEnt and Divagis were applied to analyze ande predict the suitable distribution area of Dendroctonus armandi, ROC was used to evaluate the prediction model and the prediction results, and Jackknife analysis was made on the most important environmental factors affecting the occurrence of Dendroctonus armandi. The results showed that Dendroctonus armandi had a concentrated distribution area in China, and the pest was mainly distributed in the southern part of Shanxi province, the northeasten of Sichuan province and the sotheasten of Gansu province, and the most important environmental factors affecting the occurrence of Dendroctonus armandi was the mean temperature of the driest quarter. As the global climate changes, the potential distribution range of Dendroctonus armandi will vary according to different emission scenarios. With greenhouse gases under the A1b emissions scenario, by the year 2050, the high-risk areas will not change significantly, the medium-risk areas will transfer to other places; while under A2a and B2a emission scenarios, the potential distribution of Dendroctonus armandi will have a tendency to expand in Sichuan and Hubei provinces, but the medium-risk areas will not change significantly.
