Abstract:

Based on the remote sensing monitoring data of land use change/cover in 1990, 2000, 2010 and 2018, using land use transfer matrix, eco-environmental quality index, and ecological contribution ratio of land use transition, this paper analyzes the spatiotemporal features of "Production-Living-Ecological" space structural transformation and eco-environmental effects of land use/cover change in China from 1990 to 2018. On this basis, we identify the main influencing factors of eco-environmental effects and the spatial heterogeneity by using geographically weighted regression model. The results showed that: (1) The production and living space increased, the ecological space decreased, and the overall situation was insufficient from 1990 to 2018 in the whole country. (2) The high-value areas of eco-environmental quality were concentrated to the east of the Hu Huanyong Line during 1990-2018, and mainly in the south and northeast of China. The low-value areas were mainly distributed to the northwest of Hu Huanyong Line. The squeeze of other ecological space and agricultural production space on grassland and woodland ecological space is an important reason for the deterioration of the eco-environment during the study period. (3) Slope, annual precipitation, land use intensity, elevation, topographic relief, population density, and average annual temperature were the main factors influencing eco-environmental quality pattern in China, and the spatial difference of the effect of each factor was obvious. Chinese policies on economic development should take into account the eco-environmental effect of "Production-Living-Ecological" space transformation and influencing factors in the future, and promote the rational distribution of "Production-Living-Ecological" space and the construction of ecological civilization in China.
