基于吉尼系数原理的森林资源分布非均衡性评价模型与实证研究

将西方经济学原理与中国国情、林情结合,建立了森林资源分布非均衡性评价的一般模型。实证研究发现,在第四次、第五次森林清查期间,我国森林资源的吉尼系数均大大超过世界公认的吉尼系数警戒线,已达到两极分化线,并且森林资源洛伦斯曲线有弯曲程度加大的趋势。表明在此期间虽然森林覆盖率显著提高,但森林分布不均衡特征显著恶化,部分区域生态环境仍相当脆弱。建议坚持科学发展观,将改善森林资源分布相对均衡性要求纳入我国林业战略规划。

Research on the Appraisement Model of Forest Resources Allocation Disequilibrium Based on Gird Coefficient Theory

Combining economics and Chinese national status and forest condition,this paper is to set up the appraisement model of forest resources allocation disequilibrium.This paper has found that both the forth and the fifth forest research Gini coefficients are much exceed the international warning line of Gini coefficient.Comparing with different time,the degree of the Lorenz curve is becoming higher.It predicts that the forest cover ratio increases dramatically,but the disequilibrium of forest distribution gets worse,the problem of polarized distribution is seriously.Partially local ecological environments are very frail because the local differences of forest resource equilibrium.The suggestions from the paper,to persist on science development,to bring the requirements to improve forest resource equilibrium into planning of the forest strategy in China.
