【摘要】 本文应用生态学原理,探讨了土地利用结构优化的生态标准,并将其作为衡量生态合理与否的指标。通过建立森林生态功能绿当量模型,并充分挖掘其他具有绿当量用地(主要是耕地、园地与草地)的生态服务价值的基础上,引入森林与耕地、园地、草地之间基于"绿量相当"的面积换算关系,定量测算出湖北省的区域生态绿当量,并将该值与以最佳森林覆盖率的生态优化标准进行比较,从而为土地利用结构优化调整提供参考依据,以实现区域土地利用的生态、经济、社会综合效益蕞大化。更多还原

【Abstract】 Applying the principles of ecology,this paper establishes a mathematic model of ecological green equivalent,calculates the optimal forest-coverage rate according to the reality of a district.Through considering the value of ecosystem services of land with green equivalent(mainly cultivated land,garden plot and grassland),ecological green equivalents in Hubei were calculated by introducing the area conversion between woods and crops,garden,grass.Finally,the general green equivalent and the optimal forest cover rate are contrasted based on the theory of ecological optimization.The results can be able to provide significant reference for optimization of land use structure and harmoniously development of ecology,economy and society.更多还原
