Abstract:
The effects of different fertilization treatments on the early growth of Coptis chinensis were studied by the fertilization experiment. The results showed that the different amount of fertilizer NPK had little effect on the early height growth of Coptis chinensis,but promoted generation of new leaves more than 20 days earlier, and increased leaf number in different degrees. When the fertilization amount was less than 22.5 kg per 0.067 hectare, in pace with the increase of fertilizer, new leaf number increased. When fertilization amount was 22.5 kg per 0.067 hectare, the new leaves reached the maximum of 7.52. When the fertilization amount was greater than 22.5 kg per 0.067 hectare, young leaves decreased. When fertilizer amount was less than 15 kg per 0.067 hectare, rhizome length increased from 1.26 cm to 1.44 cm with the increase of fertilizer amount. When fertilizer amount was more than 15 kg per 0.067 hectare, rhizomes length got shorter instead. When fertilizer amount was greater than 22.5 kg per 0.067 hectare, rhizome length was shorter than the control group; Fertilization had significant effects on the weight of rhizomes, especially at the fertilizer amount of 22.5 kg per 0.067 hectare, the maximum weight of rhizomes was 1.5 g, 172.92% higher than the control group (0.82 g). at the fertilizer amount of 22.5 kg per 0.067 hectare, rhizoma coptis reached the maximum yield.

Abstract:
Dendrocalamus farinosus is one of the native bamboos in Sichuan. In this study, the influence of bamboo age, even degree, uniform degree and density on bamboo yield were estimated by setting 125 sample plots which were managed in similar measures. The result showed that there were significant influence of age, uniform degree and density on bamboo yield, but the influence of the even degree was insignificant on the yield. As a consequence, it was found that the age structure(1 a~2 a prevailed), 10 values uniform degree and 10000 plants per hectare were most optimized forest structure,able to obtain the highest yield.

Abstract:
To find how the simulated nitrogen deposition affected the soil nitrogen components of Pleioblastus amarus plantation, nitrogen addition was initiated in the bamboo forest of Rainy Area of West China from November 2007, in the form of ammonium nitrate (NH4NO3).4 N treatment levels were set:control(CK,0 kg·N·hm-2·a-1), low-N(LN, 50 kg·N·hm-2·a-1), medium-N(MN, 150 kg·N·hm-2·a-1), and high-N(HN, 300 kg·N·hm-2·a-1). Samples were taken from the topsoil(0~20 cm) in November 2013, January 2014, April 2014, and July 2014. The TN, NH4+-N, NO3--N, PON, ION content of soil were determined.Results showed that,compared with the initial nitrogen deposition, the TN content of the soil increased, and the content of NO3--N increased significantly under long-term nitrogen deposition treatment, while the other nitrogen components were not significantly changed, but still had some changes.

Abstract:
In this article,tests were conducted on the seed germination of five kinds of turf grass under Cadmium stress.Comparisons were made on the changes of germination rate, germination index and toxicity rate of Trifolium repens,Medicago sativa,Cynodon dactylon,Zoysia japonica and Zoysia matrella under different concentrations of Cd2+ treatments. The results showed that higher Cd2+ concentration decreased the seeds germination rate,and increased the toxicity rate.The germination index showed a decreasing tendency to all grasses on the whole. The tolerance to Cd2+ successively diminished for Zoysia matrella,Zoysia japonica,Trifolium repens,Medicago sativa,and Cynodon dactylon. The low concentration of Cadmium treatment promoted the germination of Zoysia matrella. The study provided reference for the seed selection of turf grass in reducing Cd2+ pollution, and also laid a foundation in the study of the defense mechanism for turf grass under heavy metal stress.

Abstract:
Making use of Bethylidae carrying pathogens to prevent and control the longicorns could play advantage of active search of Bethylidae and strong pathogenicity of pathogens,better than releasing Bethylidae only or spraying microbial inoculum. However, it was necessary to ensure that the carrying pathogens would not significantly affect the Bethylidae' host search ability. In order to use Scleroderma sichuanensis carrying pathogens to prevent and control Monochamus alternatus,this paper measured the virulence of the conidial powder and spore suspensions of four strains of pathogens on S. sichuanensis. The results showed that the mortality rate of the powder spores in S. sichuanensis was higher than that of the suspension spores. When spraying spore suspension, the cumulative mortality of four strains increased along with the increasing concentration. For S. sichuanensis, the virulence of Beauveria bassiana was relatively higher than that of Metarhizium anisopliae, and the lethal rate of B. bassiana was also higher than that of M. anisopliae. Research results could provide some basis data for the selection of strains and development of microbial inoculum which was useful for S. sichuanensis carrying pathogens to prevent the M. alternatus.

Abstract:
Rural landscape bears "homesickness" feelings of modern people. Presently, rural landscape planning and protecting are being taken seriously. However, the quality assessment of rural landscape is a missing element in the rural landscape planning and protecting. This study analyzed the research status of rural landscape quality assessment since 1960s,and summarized previous rural landscape quality evaluation indexes, methods and related researches. Then,the authors took Lin Pan as an example in west Sichuan, and aiming at the insufficiency of current research, gave suggestions for rural landscape quality assessment in the future. Further research may focus on the following aspects:(1) establishing a suitable evaluation index system of landscape quality;(2) standarding operation process in the evaluation of landscape quality;(3) comparing the classification of landscape evaluation;(4) focus on landscape pattern and landscape aesthetics;(5) attaching great importance to the regional culture of rural landscape.

Abstract:
A portable electronic tree-diameter dendrometeris was developed based on a strain sensor to automatically measure and recordthe diameter of a tree. The main hardwares constituting the device were micro-electro-mechanical systems, sensor, tape and reel.Through A/D, the pulse count of the sensor was converted to the perimeter and diameter of the tree, which would be embedded in the operating software, to realize the digitization and accuracy of tree-diameter measurement. Beyond the existing product design ideas based on optical principles and mechanical principles, this study developed a new approach of integration, miniaturization, digital development of dendrometer.

Abstract:
Field monitoring plays an important role in biology conservation and biodiversity management. In some western developed countries, they have carried out the standardized regular monitoring for a long time. While in China, long-term monitoring started relatively late. The raw data of field monitoring was analyzed in Foping Nature Reserve in 2011~2012. The results demonstrated that average trace density of 9 kinds of mammals had significant differences in this area. Besides, they also had some differences in mean elevation and habitat utilization. Many species population had decreased except for giant pandas and takins (Budorcas taxicolov), on which some specific advices were given. At last, the monitoring results of Foping Reserve had reference meaning for other reserves.
