The wild animals and plants resources are rich and the ecosystem is integrity. There are well-preserved areas of native biological communities. Its strip and the region decided that on the one hand biological diversity is rich; on the other hand, there is its unique ecological fragility. Once it is destroyed, it would be very difficult to restore. In order to protect the ecological environment of wild animal and plant habitats and wild animal and plant resources, this paper uses quadrat survey procedure to carry on the investigation. In the Micangshan Forest Park's typical land sector the author establishes the sample area of 20 m×20 m to invest the tree layer of plant species and builds five 2 m×2 m the small quadrats along the type place's diagonal line machinery to invest bush level and the field layer floristic component. Again according to the Micangshan Forest Park's terrain, the vegetation and the difference humanity interference condition, the autor builds the different quantities separately the line transect to invest the animal type. This article through to eastern Sichuan Province north the Micangshan forest park biodiversity resources investigation, has analyzed the biodiversity protection work present situation and the existence question, and put forward the proposal to the next protection work.展开更多

Through standard plot investigation and method of trunk analysis, systematic research is conducted on storage and productivity of the planted forest and their relationship with site condition. As shown in the research, produc-tivity of planted forest of Larix kaempferi in low latitude area is higher than that in high latitude area while stand productivity is higher in slight acid soil. Contents of potassium element in the soil have considerable in? uence on productivity of the Larix kaempferi forest.展开更多
