【摘要】：研究林业生态安全测度评价对管理者制定林业生态安全预警、监管和控制措施以深入推进生态文明建设具有重要意义。为克服已有研究的不足,本文立足于林业生态安全的广义内涵——产业与生态互利共生,在分析林业产业压力与森林生态相互关系的基础上,利用2004-2015年全国及31省域面板数据,运用结构化PSIR和定量化SEM方法确定了林业生态安全指标及其权重,通过Lotka-Volterra方法得到了具有生态经济意义的林业生态安全共生度指数及其判据,实现由指标向指数的耦合集成,最后对全国及31省域林业生态安全实证测度,并根据测度的"系列指数"追溯"指标变量"以找出林业生态安全问题的原因,实现由指数向指标的回溯解耦。研究结果表明:(1)整个中国林业产业压力与森林生态处于非绿色共生模式导致林业生态安全处于预警状态,这将产生潜在的林业生态安全隐患,亟需引起高度重视,要实现林业绿色安全仍任重道远;(2)31省域中,处于林业生态安全预警省域的数量(18省域,占比58%)要多于处于林业生态安全省域的数量(13省域,占比42%);(3)林业生态安全不仅依赖于林业自然资源禀赋能力,还取决于林业产业压力与森林生态的共生协调状态。
[Abstract]:It is of great significance for managers to establish early warning, supervision and control measures for forestry ecological security in order to promote the construction of ecological civilization. This paper is based on the broad connotation of forestry ecological security-industry and ecological mutual benefit symbiosis, on the basis of analyzing the relationship between forestry industry pressure and forest ecology. Based on the panel data of national and 31 provinces from 2004 to 2015, the indexes and weights of forestry ecological security were determined by using structured PSIR and quantitative SEM methods. The symbiotic index of forestry ecological security and its criterion were obtained by Lotka-Volterra method, and the coupling integration from index to index was realized. Finally, the paper measures the forestry ecological security in the whole country and 31 provinces, and traces the index variable according to the series index of the measure to find out the reason of the forestry ecological security problem. The research results show that the pressure of forestry industry and forest ecology are in a non-green symbiosis mode in China, which leads to the forewarning of forestry ecological security. This will produce potential hidden dangers of forestry ecological security, and it is urgent to attach great importance to it, and there is still a long way to go to realize the green security of forestry. The number of early warning province of forestry ecological security is 18 provinces (58%) more than that of 13 provinces (42%). 3) Forestry ecological security not only depends on the natural resource endowment ability of forestry, but also depends on the symbiotic and harmonious state of forestry industry pressure and forest ecology.
