Abstract
Scientific evaluation of the comprehensive carrying capacity of land is the condition for regional coordination and high-quality economic development. Applied entropy method and expert marking to determine weight, and adopted multi-objective comprehensive evaluation model to evaluate the comprehensive carrying capacity of land resources from 2008 to 2018 in Shandong province. The results show that the comprehensive carrying capacity level is located in the lower and intermediate critical level, which has obvious spatial differences, and carrying capacities of social economic, land resource, water resource and ecological environmental are not consistent. On this basis, according to obstacle characteristics of land comprehensive carrying capacity, puts forward the proposal for space optimization pattern.
Highlights
At the second plenary session of the Fifth Plenary Session of the 18th CPC Central Committee, General Secretary Xi Jinping put forward the development concept of innovation, coordination, green, openness and sharing, which is of great guiding significance to the high-quality development of China's economy
The land is the carrier of the comprehensive system of social economy, population, resources and environment, and the quantitative measurement of its comprehensive carrying capacity is the prerequisite for achieving regional coordination and high-quality economic development
The evaluation score of the comprehensive carrying capacity of land resources in Shandong Province is 0.4042, which is at the lower and intermediate critical level.Comparing the carrying capacity levels of various standard layers of land resources, social economy, water resources and ecological environment, the carrying capacity of land resources elements is 0.5054, which is at the intermediate level
Summary
At the second plenary session of the Fifth Plenary Session of the 18th CPC Central Committee, General Secretary Xi Jinping put forward the development concept of innovation, coordination, green, openness and sharing, which is of great guiding significance to the high-quality development of China's economy. The land is the carrier of the comprehensive system of social economy, population, resources and environment, and the quantitative measurement of its comprehensive carrying capacity is the prerequisite for achieving regional coordination and high-quality economic development. Peng Wenying (2014) believe that Land resources should strengthen ecological construction and environmental protection They put forward the theory of spatial optimization pattern of comprehensive carrying capacity of land resources[4]. The comprehensive carrying capacity of land is that of a certain region to all human activities under the joint support of land, population, social economy and ecological environment system. The index system of comprehensive land carrying capacity is constructed from four aspects of land resources, social economy, water resources and ecological environment, including three levels of target layer, criterion layer and index layer, with a total of 16 evaluation indexes.
