农用地景观生态功能评价

在对农用地景观生态评价科学理念分析的基础上,构建了一套农用地景观生态功能评价的指标体系,采用多目标线性加权函数法进行综合测算,得到土地利用巨系统中的林地、耕地、草地等六大子系统的景观生态功能指数,并通过对比分析揭示了农用地特殊而优越的景观生态保护功能,提出了合理配置农用地资源,建立农用地转用的景观生态补偿机制的建议.

Evaluation of Arable Land''s Landscape Ecological Function

On the basis of analyzing the scientific thinking of arable land's landscape ecological evaluation, this paper constructs a set of index system to evaluate the arable land's landscape ecological functions and uses the method of multi-objective linear weight function to synthetically calculate. Including arable land in land using system, six sub-systems' landscape ecological function indexes are obtained. Arable land's special and superior landscape ecological and protective functions are reflected by comparatively analyzing. The suggestions such as collocating the resources of arable land properly and establishing changed arable land's landscape ecological compensation mechanism are proposed.
