Ecosystem services assessment of ecological conservation redlines based on multisource remote sensing data
The ecological conservation redlines is the guarantee and the maintenance of national ecological security bottom line and lifeline.Regular organization of supervision and evaluation of the ecological function of the ecological conservation redlines and understanding of the ecological function within the ecological conservation redlines are the basis for carrying out supervision and evaluation of the ecological conservation redlines.Jiaozhou City,as a pilot county for ecological environmental supervision of ecological conservation redlines in Shandong Province,based on the technical specifications of ecological conservation redlines supervision,carried out single factor and comprehensive grading evaluation of the ecosystem functions of terrestrial ecological conservation redlines in Jiaozhou City by using geospatial analysis technology,and comprehensively analyzed the spatial differentiation characteristics of regional ecosystem functions.The results show that:The total ecosystem function value of the land ecological conservation redlines in the city is about 2.148 billion yuan.The areas with excellent comprehensive ecological function index are mainly distributed in Shaohai National Wetland Park and the downstream wetlands of Dagu River(Jiaozhou Section),and the areas with good comprehensive index are distributed in the middle reaches of Dagu River(Jiaozhou section)and Shibadaohe Reservoir.The comprehensive index is generally distributed in the wetland and artificial forest in the upper reaches of the Dagu River(Jiaozhou section)and the farmland in the middle and upper reaches of the Dagu River(Jiaozhou section).By carrying out ecological function assessment of the ecological conservation redlines,in-depth analysis of the spatial differentiation,existing problems and causes of the ecological system function value will provide an important reference for the competent authorities to grasp the stability of the ecological function of the ecological conservation redlines,and carry out the assessment of the ecological conservation redlines protection effectiveness,ecological compensation standard calculation and daily supervision.
