依据基尼系数的基本内涵,构建了基于森林资源和水资源的生态安全评价模型。以江西省为例进行实证研究,结果表明:(1)江西省森林资源和水资源的16项评价指标总体达标率为81.25%,数量化评价结果为:生态环境安全等级较高,但资源分布结构有待进一步优化;(2)区域经济的不均衡发展(GDP结构不合理)是影响江西省生态安全的一个关键性因素,绿色GDP及其贡献率对区域生态安全的意义重大;(3)森林面积与GDP的基尼系数最大(0.4794),废污水排放量与GDP的基尼系数最小(0.0546);(4)从水资源总量与森林面积的基尼系数(0.0749)和森林蓄积的基尼系数(0.1103)可以从另一角度证明森林具有涵养水源的生态功能。最后,提出以"科学发展观"为指导,坚持"全面、协调、可持续"的森林资源和水资源发展利用方向,实现江西由生态大省向生态强省的跨越。
According to the basic connotation of Gini coefficient,an eco-safety evaluation model based on forest resources and water resources has been established.Taking Jiangxi Province as an example an empirical study was conducted,the result showed that:(i) the general attainment rate of 16 evaluation indicators of forest resources and water resources in Jiangxi Province is 81.25%,the safety level of eco-environment is higher,but the resources distribution structure needs to be further optimized;(ii) the unbalanced development(the makeup of GDP is unreasonable) of regional economy is a key factor influencing eco-safety in Jiangxi Province,green GDP and its contribution play a significant role in regional eco-safety;(iii) the Gini coeffi-cient of forest area and GDP is maximum(0.479 4),the Gini coefficient of waste water discharge and GDP is minimum(0.054 6);(iv) from the Gini coefficient of total water resources and forest area(0.074 9) as well as forest volume(0.110 3),it can also be proved that forest possesses the ecological function of conserving water resources.From the study,the authors conclude that the development and utilization of forest and water resources should take "scientific development thought" as guidance and adhere to "overall,coordinate and sustainable" developing and utilizing direction so as to enable Jiangxi Province to transfrom from a large ecological province to a powerful ecological province.
