南水北调河北省受水区近50年生态环境演变研究

Research on Ecological Environment Evolution in the South to North Water Diversion-Related Area of Hebei Province in Recent 50 a

选取人类活动对河北省生态环境影响最剧烈的1950s—2000s初期,从气候、水环境、土壤及环境地质、土地利用/覆盖、社会经济等角度,分析河北省中南部平原,即南水北调河北受水区的生态环境演变状况,为研究南水北调工程实施对生态环境变化的影响及河北省生态省建设提供科学依据。

In the recent 50 a, with the rapid development of technology, expansion of population etc., human activities impacted the nature environment much stronger than ever, accompanied with climate change, ecological environment of central - south plain of Hebei Province has made a remarkable change.With the aid of advanced technique as RS and GIS, together with abundant records in paper or digital format,it is feasible to study the ecological environment evolution on a time scale of few decades. The 1950s- 2000s time slice, during which the ecological environment of Hebei Province was impacted strongly by human activities, are ,selected to study the evolution of ecological environment in south to north water diversion - related area in Hebei Province. Different time- series data are compared from the aspects of meteorology, water resources,soil, geology, LUCC,social economy, to analysis the evolution. Finally the driving forces of the evolution are discussed. South to north water diversion is a big project which can strongly influence the eoological environment of the study area,therefore the research prepared a foundation for further study about the project＇s impacts on ecological environment.
