| 摘 要： | 基于生态绿当量构建土地利用结构优化模型,以江西省新建县为例对区域土地利用结构优化进行定量研究。在研究过程中,通过计算耕地、草地等地类的生态绿当量得到研究区域的综合绿当量,并将该值与以最佳森林覆盖率的生态优化标准进行比较,进而对研究区域土地利用结构进行优化调整,以期达到生态优化。

| Abstract: | Applying the iclea of ecological principles,this paper establishes a mathematic model of ecological optimization of land use structure based on green equivalent.In this study,the area conversions between woods and crops,between woods and corner,and between woods and grass were introduced based on the rule of green equivalent.And then the value of ecosystem services of theirs was assessed.On this basis,the general green equivalent and the optimal forest cover rate were contrasted based on the theory of ecological optimization.Finally,the land use structure was fested and verified with Xinjian County in Jiangxi Province as a case. |
