基于民族山区生态与产业共生关系的林业生态安全评价——以云南省昌宁县为例

Evaluation of Forestry Ecological Security Based on Ecology-Industry Symbiosis in Ethnic Mountainous Areas--the Case of Changning County,Yunnan Province

通过生态与产业共生视角探究云南省昌宁县产业和林业生态的相互作用关系,运用森林生态与林业产业复合系统的Lotka-Volterra共生模型,构建“压力—状态—影响—响应”指标体系,结合林业L-V模型和特征指数分析昌宁县生态安全状况,实现生态安全级别及预警级别判定。结果表明:昌宁县2011—2015年均处于林业生态安全预警转折区,位于康复状态与健康状态临界点之间;2019年以后处于生态安全区,林业生态水平逐步恢复并向产业-生态互利共生方向发展,但林业生态相对处于劣势,仍需在今后决策和发展中引起重视,在发展林业产业的同时进一步推进生态保护,使其朝着更为稳定的共生方向发展。

Through the ecological and industrial symbiosis perspective to explore the interaction between industry and forestry ecology in Changning County,Yunnan Province,using the Lotka-Volterra symbiosis model of forest ecology and forestry industry composite system,constructing the′Pressure-State-Impact-Response′index system,and analyzing the ecological security status of Changning County by combining with the forestry L-V model and the characteristic index.The environmental security status of Changning County was investigated,and the ecological security level and early warning level were determined.The results show that Changning County was in the early warning turning zone of forestry environmental security from 2011 to 2015,located between the critical point of rehabilitation state and healthy state;after 2019,it was in the environmental security zone,and the forestry ecological level is gradually recovered and developed in the direction of industry-ecological mutual benefit symbiosis,but the forestry ecology is relatively in a disadvantageous position,and it still needs to be paid attention to in future decision-making and development However,the forestry ecology is relatively disadvantaged and still needs attention in future decision-making and development,further promoting ecological protection while developing the forestry industry,so that it can grow in the direction of a more stable symbiosis.
