Abstract： This study attempts to measure the eco-environmental effects of land use transformation in northwest China from 2000 to 2020 based on the perspective of land“production-living-ecological”function. For this, the study employs the eco-environmental quality index and ecological contribution rate model, and comprehensively uses hot-spots analysis tool, Geo-detectors tool, and other methods to discuss the evolution characteristics and differentiation mechanism of eco-environmental quality. The findings of this study show: (1) The“production-livingecological”space in northwest China shows significant spatial differentiation, indicating an increasing trend of production and living space and a decreasing trend of ecological space. (2) The eco-environmental quality index increased from 0.22720 in 2000 to 0.22724 in 2010 and then decreased to 0.22699 in 2020, although the overall eco-environmental quality remained relatively stable. The change in eco-environmental quality exhibited both improvement and deterioration. The improvement of eco-environmental quality mainly depends on the protection of regional ecological space, while the deterioration of eco-environmental quality is that agricultural production land occupies ecological land in pastoral areas. (3) The eco-environmental quality is spatially characterized by“high in the southeast, second in the northwest, low in the middle”. The cold-spots and hot-spots in the evolution of the eco-environmental quality pattern are mainly concentrated in the southeast and northwest regions and have the same spatial distribution as the population and industry in the area. (4) The proportions of ecological land use, normalized vegetation index, and human active index were the leading factor of spatial differentiation of eco-environmental quality; the interactions between the influencing factors mainly include nonlinear enhancement and bifactor enhancement. The internal interaction of natural factors and the interaction between natural factors and socio-economic factors affected the spatial differentiation characteristics of eco-environmental quality in northwest China. The results of this study may provide a theoretical basis for the optimization of the national land spatial pattern and ecological environment protection in northwest China.

Abstract： Exploring the long-term fusion mechanism of agro-cultural-tourism is an important measure to realize the sustainable development of rural areas and implement the rural revitalization strategy. Therefore, the directory data representing the development level of agro-cultural-tourism are selected as the research object, and the coupling coordination degree and geodetector and Moran’s I index are comprehensively used to explore the spatial differentiation characteristics and influencing texture of the coupling coordinated development of agro-culturaltourism in China quantitatively. The following results are obtained. (1) The development level of agriculture, culture, and tourism is not synchronized and the spatial distribution is uneven, each forming its unique spatial distribution characteristics. (2) Under the market-oriented operation, the integrated development of agricultural culture and tourism shows the characteristics of“cultural tourism first, agriculture lags behind”, nearly half of the prefecturelevel cities are coordinated, and the spatial coupling coordination is general. (3) From the overall perspective, the agglomeration characteristics of the spatial coupling and coordinated development of agro-cultural-tourism are remarkable, and the local spatial autocorrelation exhibits a differentiated feature bounded by the Hu Huanyong line. (4) The explanatory strength of the spatial differentiation of the coordinated development of agro-cultural-tourism coupling is innovation level>sociocultural>physical geography>economic development. This finding reflects the initiative of people, especially the innovation ability, is the leading force to the coupling and coordinated development of agro-cultural-tourism. (5) The spatial differentiation of the coordinated development of agro-cultural-tourism coupling is affected by complex coupling effects of multiple factors, and the interaction effect between innovation level and sociocultural dimension is significantly higher than that between physical geography and economic development dimension. Thus, this study presents the following suggestions. First, promoting the primary, secondary, and tertiary industries in parallel, coordinating agro-cultural-tourism, carefully considering the capital going to the countryside, conducting rural planning in advance, and demarcating land development boundaries are necessary for rural development to prevent disorderly development and construction in the capital boom and avoid wasting a considerable amount of resources. Second, rural development must combine the cultural background and develop characteristic agriculture based on resource endowments; take the revitalization of talents as a guide; strengthen cultural, industrial, and agricultural technology innovations; and form a coordinated development pattern of“people-land-industry”.
