Description
The region around Qinghai Lake has a high level of ecological environment protection and high quality to build an international eco-tourism destination demonstration area, but the current concentrated and disorderly tourism construction has caused a certain degree of impact on its ecological security. How to evaluate the ecological security situation of the county around Qinghai Lake scientifically, identify the safe development area and the main obstacle factors, is an urgent problem to be solved.Therefore, this paper takes 7 counties around Qinghai Lake as the research object, and constructs the ecological security evaluation index system by using DPSIRM(driving force - pressure - state - influence - response - management) model through remote sensing image, POI data and other multivariate data.The linear weighting method was used to calculate the ecological security evaluation value and comprehensive value, and the ecological security evaluation value was divided into five levels: risk level, sensitive level, critical level, general level and good level, and the priority sequence of tourism construction was carried out according to the ecological security level. The results showed that: (1) the ecological security level of the counties around Qinghai Lake was increased from the critical level to the general level, and the overall situation was in a steady trend of good development. However, the local space shows that the three counties around the lake are at a sensitive level. (2) The pressure subsystem and response subsystem are the main factors affecting the ecological security of counties around Qinghai Lake region. Among them, the development of animal husbandry, the growth of tourist population, and environmental governance account for a larger proportion of GDP. (3) The strategy is to rationally arrange the layout of cultural tourism projects and evacuate tourists; Optimize and improve infrastructure, improve service; Control and implement ecological animal husbandry, reduce stress. The research results can provide decision-making reference for the development and construction of counties around Qinghai Lake area and the coordinated sustainable development of ecological environment, and have reference significance for the ecological safety evaluation of other counties around lake area.
