摘要: 【目的】 研究城市湿地公园土地利用方式对水环境质量的影响,以期为城市湿地公园和具有较大水体公园的规划建设和优化提供参考和依据。【方法】 通过GIS空间分析技术计算湿地公园土地利用情况与其对应的表征土地利用强度的景观开发强度指数,运用Pearson相关分析探讨土地利用方式对水环境的影响后发现:【结果】 ①道路面积对水环境的COD指标有正向影响。②林地对DO值有较大影响,并对水质有一定的缓冲与净化作用。③缓冲半径与土地开发强度具有正相关关系,开发强度在一定范围内对水环境质量有正向作用。【结论】 以水体湿地边缘的任意点建立缓冲半径,当缓冲半径在164.8~244.8 m时,土地利用开发强度(LDIindex)控制在3~4.2之间,对湿地公园水环境质量是最有利的。

Abstract: 【Objective】 This study aims to analysis the effect of urban wetland park land uses on water environment quality to provide reference and basis for the land use planning and optimizing of urban wetland parks and parks with large water bodies. 【Method】 Based on GIS spatial analysis technology, this study calculated the land uses of wetland park and the corresponding landscape development index representing the land use intensity. The Pearson correlation analysis is used to explore the impact of land use on water environment. 【Result】 ① The road area has positive influence on the COD index of water environment. ② Woodland has a great influence on the DO value and has a certain buffer and purification effect on water quality. ③ The buffer radius has a positive correlation with the land development intensity. Land development intensity within a certain range has positive effect to the water environment quality. 【Conclusion】 To build a buffer radius at any point at the edge of the water body,when the buffer radius is between 164.8 and 244.8 m, the use of the land (LDIindex) is controled between 3 and 4.2 will be the most advantageous to the water environment in the wetland park.

Key words: land use, land development intensity, wetland park, water environment
