Description
Summary:The man-land system is a macro system consisted of nature, society and economy, which is of great significance to the regional management and sustainable development. However, the system presents many challenges and disharmonies especially in river basin regions. It is not only the largest area where human disturbances occur but also the most concentrated area of anthropogenic activities. So, the Xijiang River Basin in Guangxi, which is one of the emerging national strategies, was taken as the study area. And the man-land system of the study area can come down to the resources and environment subsystem and social economy subsystem. First, the evaluation index system was established by selecting 25 relatively evaluation indexes. The variable coefficient was applied to calculate the index weight. Then, the coupling model, which was developed based on system theory, was introduced to figure out the coupling degree and coupling coordination degree of the man-land system of the study area. The results indicated that the development of social economy system presented ascending trend accompanied with resources and environment system presented fluctuated ascending trend. From 2005 to 2014, the coupled states of the man-land system developed from low level harmonize to medium level harmonize.
