Our country has 300 million hm2 forest, among them, the state-owned forest land 124.16 million hm2, accounting for 40% of the total forest area; There are 186.3 million hm2 collective forest land, accounting for 60% of the total forest area. How to use without damaging the ecological environment system on the basis of rational utilization of forest resources, improve the living standards of the forest, make the forest ecosystem and forestry industry to form a virtuous cycle, need a detailed understanding of the relationship of forestry ecological and forestry industry, establishment and optimization of forestry ecological security pattern.Through field investigation and file access methods wengyuen county forestry ecology and industry related information collection, analysis of wengyuen county forestry development. Combined with the scholars on the basis of related literatures on ecological safety, and study of forestry ecology, landscape, analysis and screening of forestry ecological security pattern evaluation index. Make further screening at the same time, according to the coefficient of variation, and finally to build the evaluation index system of forestry ecological security pattern, including the industrial level, the ecological level, the environmental capacity of 3 standards, 24 indicators. Using the Delphi method combined with AHP method, using Yaahp(0.5.3) software, integrated to determine the weight of each index. At the same time, according to the standard of sustainable forestry management, the local forestry development requirements, field research analysis and expert advice to determine the reference value. Then calculate the Wengyuan county forest ecological forestry industrial symbiosis degree stress index using the L-V model, finally through the double characteristic index of forestry ecological security level evaluation of Wengyuan County Forestry Ecological pattern.According to the forestry ecological safety evaluation method and pattern of L- V model, calculation of wengyuen county industry force index is 1.8115, the ecological level of stress index is 0.0017, the symbiotic index is 1.0010, the final judgment Wengyuan County belongs to the ecological security health level safety(green security). Through symbiosis index s(k) of the calculation formula and the judgment standard, the greater the symbiotic industry and ecological status, the better, tend to be mutually beneficial symbiosis(also called green symbiosis), Wengyuan County of symbiosis index for S(k) =1.0010 symbiotic weak. Wengyuen county forestry ecological security pattern is in healthy condition, but also should pay attention to the balance between ecology and industry development, otherwise easy to sub-health of regional development.According to the result of wengyuen county forestry ecological security evaluation, analyze the restricting factors, it is concluded that the problems mainly include:(1) the forestry industrial structure need to be further optimized, the third industry development lag behind;(2) structure unreasonable forest resources, forest category structure is single;(3) the ecological public welfare forest stand quality is not high;(4) the public's perception of forest culture is not enough.Based on this, advances wengyuen county forestry ecological security optimization Suggestions:(1) the use of the concept of value chain guide forestry industrialization development;(2) make full use of forestry resources, adjust measures to local conditions for the development of forestry industry.(3) the implementation of forest land classification grading protection;(4) to promote forest management planning and compilation work of forest management plan;(5) a solid resource management Lin, strict control of forest land requisition;(6) strengthen the propaganda forest ecological culture, improve citizen consciousness of ecological protection.
