Study on the ecological effects of the spatial transformation of the Production-Living-Ecological Space in Guangxi

Abstract

Guanxing was determined as the study area, and the characteristics and formation mechanism of the transition of "production-life-ecology" were analyzed from 1990 to 2018 by transfer matrix model, habitat quality index model and ecological contribution rate model. The results showed that: 1) The area of production and living space increased by 299.72 square kilometers and 900.34 square kilometers respectively, while the area of ecological space decreased by 1200.06 square kilometers; 2)The high-quality ecological environment zones are distributed in the northern areas with higher elevation, the medium-quality zones are distributed in the central plain areas,and the low-quality zones are distributed in the southern coastal areas; 3)The ecological environment quality changes from population and natural environment as the main controlling factors gradually turned to the driving mechanism of the policy system, socio-economic and demographic factors.Thus, It is an effective measure for Guangxi to deal with the ecological environment problems by reducing the speed of the production and living space crowding out the ecological space in the central plain and the southern coastal areas, and reducing the disturbance of human economic activities to the land space in the severe rocky desertification area in the north.
