摘要

运用灰色关联度分析法

研究了高原湖滨区滇池流域建设用地的景观格局指数与滇池水体的TN

TP浓度变化之间的关系。结果表明

1988-2008年

滇池草海与外海TN

TP浓度呈不断上升的趋势;滇池流域建设用地斑块的团聚程度和整合性升高

建设用地斑块间距离变小

大面积的建设用地增多

且建设用地斑块形状趋于复杂

具有不规则的特征;滇池流域建设用地对水质的影响与其景观空间格局关系密切

特别是聚合度和面积加权的平均斑块分维数。要保证该地区迅速发展的城市化背景下的水环境安全

滇池流域土地利用调整的基本方向是在湖滨带地区

保留足够的生态用地

避免建设用地的过度整合及大面积建设用地的形成。

Abstract

Grey correlation coefficient analysis was employed to explore the relationship between landscape pattern idices of constraction land in Dianchi Lake basin and water TN

TP concentrations in Dianchi Lake. The results showed that the concentration of TN and TP in Caohai and Waihai of Dianchi Lake had been increasing obviously during 1988-2008;In Dianchi Lake basin

the agglomeration and integration level and size of construction land patches increased constantly while the distance between the land use patches decreased

the shape of the land use patch tends to be more complex and irregularly;the impacts of construction land use on water quality were closely related with the spatial land use pattern

especially the degree of polymerization and the mean area-weighted of fractal dimension.To guarantee the water safety for the rapid development of urbanization in Dianchi Lake basin

the basic land-use adjustments to retain sufficient ecological land in the lakeside area

to avoid the excessively integration of construction land and the formation of big size of construction land patches was proposed.
