摘要
在GIS支持下,以生态功能指数(E)作为农业景观生态功能的量度指标,以福建省漳浦县马坪镇作为研究区,划分景观评价单元,在各景观单元评价过程中充分考虑到作用于景观生态功能的各类指标及其权重,并利用隶属函数计算出各指标对景观生态功能的贡献率,最后计算出每一景观单元E值,并根据其频率分布进行景观生态功能分区,结果符合研究区实际情况,为进一步的景观生态设计和规划提供了必要的科学依据,同时也为景观生态功能的量化研究提供参考。
On the base of GIS, Maping Town, Zhangpu County, Fujian Province was zoned into units to evaluate the landscape with the index of ecological function (E) as measuring parameter of agro-landscape ecological function. Every parameter and its weight were calculated and its function ratio was analyzed by using subjection function. E value of every unit is calculated. And the landscape ecological function zoning was conducted according to E frequency of every unit. The zoning results are consistent with the practical ones and provide a scientific support for the landscape ecological design.
