Evaluation of Natural Resources and Environment Carrying Capacity for Yangtze River Economic Belt Based on UAV Remote Sensing and Artificial Intelligence:Taking Datong Town in Qichun County as an example
Promoting the development of the Yangtze River Economic Belt is a major strategic decision of the state,and the coordinated development of natural resources,environment and economy and society is the objective need of ecological civilization construction.At present,there are many research results on the evaluation of natural resources and environ-ment carrying capacity,but most of them do not fully consider the six elements of'mountains,rivers,forests,fields,lakes and grass'.In addition,with the development and application of UAV technology,high-precision natural resources and environmental factors can be obtained by using UAV remote sensing technology.Therefore,based on the concept of'mountains,rivers,forests,fields,lakes and grass'life community,four first-level indicators such as land resources and 11 second-level indicators such as per capita cultivated land area were selected,and the evaluation system of natural resources and environment carrying capacity was established by use of the analytic hierarchy process.Datong Town,Qi-chun County,Huanggang City,which is located in the middle of the Yangtze River economic belt,was taken as an exam-ple.The distribution law of seven indicators such as per capita cultivated land area is obtained through remote sensing im-age interpretation for high-precision ortho image data collected by UAV,and the distribution rules of four indexes such as population density were obtained according to the statistical data.On this basis,the evaluation results of natural resources and environmental carrying capacity were obtained by using ArcGIS spatial analysis function.The results show that the proportion of villages with high carrying capacity,medium carrying capacity and low carrying capacity was 19％,55％and 26％,respectively.In general,the natural resources and environmental carrying capacity of the research area is at or above the medium level.This paper enriches and expands the research ideas and methods of the traditional resource and environment carrying capacity assessment,and the research results provide the basis and support for the management de-partment to make regional development plans and ecological protection and restoration schemes.
