滇池流域土地利用变化及其对水质影响研究综述
Research review on land use change in Dianchi Lake Basin and its impact on water quality
摘要
Abstract
Land use change is an important driving factor of surface water quality,especially in the plateau lake basin where hu-man activities are strong.Dianchi Lake Basin is one of the key areas for the construction of ecological safety in the upper reaches of the Changjiang River.However,rapid urbanization in recent decades has caused water quality deteriorate rapidly.It is urgent to comprehensively summarize the relevant issues in order to achieve regional sustainable development.229 papers on land use change and water quality in Dianchi Lake Basin were obtained by keywords research.Research content and methods,land use change characteristics and its water quality effects were systematic analyzed,and the impact of land use change on water quality was the focus.The results show that there are differences in the land use classification system,research time period,data resolu-tion,and water quality parameters.In overall,the most significant changes are on construction land increasing and cultivated land decreasing since 1974.The most sensitive area for changes is the lakeside zone.Water quality has declined significantly,but the type,intensity,and pattern of land use changes have non-linear characteristics in their impact on water quality.In the future,it should further strengthen the mechanism research on land use change on water quality in Dianchi Lake Basin,and provide impor-tant support to optimize the land use of basin and protect the water quality of Dianchi Lake.关键词
