基于熵权灰度关联法的国有林区生态环境脆弱性分析

从国有林区经济、生态、社会复合系统的特点和脆弱性评价的独特性出发，设置评价指标体系，运用熵权法确定各个评价指标权重，通过灰色关联分析对指标进行分析与评价；以伊春市为分析对象，收集林业区域2002-2009年度的统计资料开展实证研究，对脆弱性影响因子的演进规律和经济内涵进行深入分析；评价体系力求突出指标的精炼性、数据的可获性、评价方法的科学性和实践可行性，核心在于为国有林区生态环境的脆弱性评价提供一种科学的定量分析方法，继而为国有林区规划和调整策略的制定提供可靠的参考依据。

Frangibility Analysis of State-owned Forest Environment Based on the Entropy and Gray Correlation Method

From the view of the characteristic of frangibility evaluation of economic, ecological and social multiple system, this article establishes evaluation model of state-owned forest based on gray relative forestry area from 2002 to 2009 year for empirical disciplinarian and economic connotation of frangib indexes system and constructs frangibility evaluation analysis method. This article collects statistical data of research, carries our in-depth analysis on propulsive ility impact factors. The evaluation system emphasizes that evaluation indexes are accurate, statistical data can be acquired and evaluation method is scientific and practical. The essential innovation of this article is to establish a scientific quantificational analytical method for the frangibility evaluation of forestry system in order to provide dependable referenced information for the programming and strategy of forestry system.
