Hebei Province Water Resources And Water Environment In Its Ecosystem Services

Water, as a kind of special ecological resource, is a foundation of supporting the system of whole life on earth. Water ecosystem not only offeres the foundation of production and life for mankind, but also have a function of maintaining natural ecosystem structure, ecological course. Water ecosystem service function refers to requirement and utility of natural environment that is formed and kept by water ecosystem and water ecological course. The quantitative and qualitative assessment of service function of water ecosystem is helpful to know the value of the water resource in an all-round way, to utilize the water resource scientifically and rationally, to reach most benefit of ecological benefits and economic benefits of water resources utilization.This research combines characteristic of distribution of space-time , development and utilization state and subject matter existing of the water resource in Hebei and water environment, coerce the sensitiveness , water environmental pollution sensitiveness , ability to control oneself of source of water and flood to regulate and store the function importance etc. through analysing the water resource in Hebei, carry on the ecological service function of water of Hebei and appraise , offers scientific basis for protect in order and the sustainable utilization water resource and water environment.1.Adopt many kinds of research means, appraise to the water resource environmentThis text uses such theories as ecology , environmentology , hydrology , sustainable development and systematic theory ,etc, analyse according to theory analysis and real example, qualitative analysis and quantitative analysis, such principles as section analysis and course are analysed, regard such characters , data materials as the statistics of every relevant departments of social economy , research paper ,etc. as the foundation, adopt geography method , mathematics and physics statistical method and GIS technology, from the standing of area, system, analyse in depth the laws of distribution of space-time and development and utilization current situations of the water resource in Hebei and water environment. Mathematics model and single factor index of using the water resource to appraise , interior plum index go on ration and qualitative appraisal to water resource and ink environment of Hebei,have summarized the water resource in Hebei and environmental question of water. On this basis, an index system set up the ecological sensitiveness of water and ecological service function and appraised , utilize Arcgis software to coerce the sensitiveness to the water resource in Hebei, water pollution sensitiveness , water resources protection importance , source of water nourish and cherish the importance and flood and regulate and store such ecological service functions as the importance ,etc. and analyse the room, propose solving the water resource crisis of Hebei, improve the pertinence suggestion of water environment.2.Temporal and spacial distribution of water resource amount of and analysis of water environmentalThe space distribution of the annual precipitation in Hebei is affected by such factors as the climate , topography ,etc. It reduces from the total trend to face the wind by Taihang Mountain , swallow mountain slope many rain belt reduce to the Northwest and southeast both sides separately. Surface water and groundwater resources amount count with sea Henan department and Luangge river and the east coastal and most large Ji according to basin person who divide into.The polllted reaches of Hebei province mainly distribute near the large and medium cities and downriver. The length of rivers which cannot be used is increasing year by year, and there is no sign of favorable turn of river water quality . The lakes in Hebei have a obvious trend to get salty, and reservoirs face threats of entrophieation generally. The underground water quality is influenced deeply by pollution of Middle Eastern area , salt water area of littoral plain and cities .The mineralization, hardness , chlorid...
