Based on the land use data of Xinxiang City from 2010 to 2020, this study integrates the methods of dynamic degreetransfer matrix, landscape pattern index and geographical detector to explore the quantitative structural changes, mutual transformations and landscape pattern characteristics of the “production-living- ecological space” (PLES) in Xinxiang City, and also analyzes the driving factors that affect the characteristic changes to reveal the laws governing the changes in the PLES and the current land use process. The results of this study reveal four important aspects of this system. (1) The changes in the PLES in Xinxiang City have accelerated significantly, and the overall performance shows that the production space continues to decrease, the living space keeps increasing, and the ecological space changes are more stable. (2) Regarding the spatial transfer characteristics, the ecological space has mainly transformed to production space, and the production space has mainly transformed to living space. (3) The landscape pattern characteristics show that the landscape types in Xinxiang City are diversified in terms of their components. (4) The spatial differentiation of the PLES is influenced by the combined effect of socio-economic and natural factors. Based on the empirical research results, we can not only propose corresponding optimization strategies for the better utilization of the PLES in Xinxiang City, but also provide important scientific references for the high-quality development of the prefecture-level cities in the Yellow River Basin.

Finance is at the heart of the modern economy. Through the results of the location Gini coefficient, it is known that from 2012 to 2019, under the background of the trend of financial space agglomeration in China, the Yellow River Basin and Henan Province, Kaifeng's financial industry has continued to rise in the national city rankings, and the development of the financial industry has shown progress. Based on the DPSIR-TOPSIS model. Overall, the security of the financial ecological environment in Kaifeng City from 2012 to 2019 has shown an upward trend, but it has been in an unsafe state, and its security situation is still not optimistic, and there is still a huge gap from the security state. As far as each subsystem is concerned, the security status of each subsystem of ecological environment security in Kaifeng City has shown a gradual upward trend, and the driving force system, state system and response system have changed from the unsafe state in 2012 to the critical security state in 2019;The affected system has been in an insecure state and showing a downward trend; The pressure system has changed from a safer state in 2012 to an unsafe state in 2019.Therefore, suggestions are put forward for the development of the financial ecological environment of Kaifeng City.

Exploring the relationship between land use change and landscape patterns can provide a basis for regional ecological management. In this paper, based on remote sensing images of the Huai River Ecological and Economic Zone for the years 2000, 2005, 2010, 2015 and 2020, the spatial and temporal evolution patterns of land use in the region were quantitatively described by using the methods of land use shift matrix and landscape pattern analysis. The relationship between land use change and landscape pattern was analyzed with the Grey Relation Analysis (GRA) model. The results show that: (1) the land use of the Huai River Ecological and Economic Zone has changed significantly in the past 20 years, with the conversion of arable land into construction and forest lands, in addition to the growth of water areas and a decline in the areas of arable land, grassland and unused land. (2) The landscape pattern fragmentation of each type of land in the study area from 2000 to 2020 fluctuated and decreased, and the landscape connectivity and landscape diversity increased significantly. (3) The GRA model shows that construction, arable and forest lands played the most significant role in the change of landscape pattern of the Huai River Ecological and Economic Zone. Countermeasures are proposed to better coordinate and optimize the relationship between spatial development and landscape pattern for the Huai River ecological and economic Zone.
