东江源水功能区水质时空变化与环境保护政策分析

Correlation analysis between Dongjiang source's spatial and temporal variation of water quality and protection policy

本文基于东江源地表水功能区时间序列水质数据,采用季节性肯达尔检验法和Arc GIS空间分析技术,分析了水功能区水质时间、空间变化特征,验证相关政策、措施的实施效果,并为进一步改善和保护东江源区生态环境及落实生态补偿政策提供参考与指导.

According to the water quality time sequence data of DongJiang source＇s surface water functional area, and by using seasonal Kendall testing method and ArcGIS software, this paper analyzed the characteristics of spatial and temporal variation of water quality about this water functional area.And we verified the complementation effect of the relevent policies and measures. The suggestion was proposed in order to improve and protect furtherly the ecological environment of Dongjiang Source Area and carry out the ecological compensation policy.
