生态绿当量在土地利用结构优化中的运用研究--以重庆市江北区为例

基于森林生态功能绿当量概念的提出与模型的建立,以重庆市江北区为例将其运用于土地利用结构优化工作中通过计算草地和农田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,对研究区域的土地利用结构进行现状评价,在此基础上对研究区域土地利用结构进行优化调整,以期使该区域土地利用实现生态、经济、社会三效益的协调,达到最佳综合效益.

The Application of Ecological Green Equivalent on Land Use Structure Optimization--A Case Study of Jiangbei District, Chongqing

Land use optimization is known as one of the most important problems in China.This paper focuses on this issue in three aspects: to establish a mathematic model of green ecological equivalent;on this basis, to introduce the area conversion among forest,crops and grass and cultivate the general green ecological equivalent;to contrast the general green ecological equivalent and the optimal forest cover rate based on the theory of ecological optimization,then verify the land use structure with Jiangbei District as an example.The aim is to make the profits of ecology,economy and society develop harmoniously.
