基于生态绿当量的开封土地利用研究

基于生态绿当量的提出与模型的建立,计算水田、旱田、园地和林地的生态绿当量,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。以开封为例,针对开封土地利用问题,提出优化方案,以期达到经济、社会和生态效益的统一。

The Application of Ecological Green Equivalent on Land Use Structure Optimization and Example

Land use optimization is known as one of the most important problems in China. Optimization of land use structure consists of economic and social and ecological optimization.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 value of ecosystem services of them was asse...
