The construction of green infrastructure (GI) plays an important role in improving the rural ecological functions and building a green livable environment. In this paper, the methods of morpho spatial pattern analysis (MSPA) and space syntax analysis are used to study the GI network construction in Suining County, Jiangsu Province. The results show that: (1) In 2018, the area of ecological patches increased by 110% compared with 1998, and the utilization rate of the GI network was significantly improved. (2) A total of 66 ecological corridors were analyzed in the county, and the main corridors were distributed in the central and western regions. The correlation analysis of core ecological patches in 1998, 2008, and 2018 proved that location factors had the greatest impact on the results of function and connectivity. (3) According to the optimization results, ecological benefits can be improved through engineering measures to realize the revitalization and development of regional rural areas.

The protection and utilization of ecological environment are very important for urban and rural development. At present, a large number of relevant theoretical and practical explorations have been carried out, which confirms the important conclusion that lucid waters and lush mountains are invaluable assets. The sustainable development of ecological environments is based on coordination with human production and life. In this paper, by constructing an accounting system for the gross ecosystem product (GEP) applicable to Hanwang town, using the market value method, the alternative cost method, the travel cost method, the willingness to pay method and other technical methods, the GEP of Hanwang town is calculated from three aspects: product supply, regulation service and cultural tourism. Finally, the spatial distribution characteristics of value are used to guide the development and layout of ecological industry in Hanwang town. The results showed that the total ecosystem product value of Hanwang town in Xuzhou was relatively high, reaching 1.165 billion CNY, with per capita reaching 30 million CNY, which was 49.16% of the town’s GDP in 2020. The value of cultural tourism is 820 million CNY, the value of regulatory services is 239 million CNY, and the value of product provision is 106 million CNY. The ecological value of Hanwang town varies greatly in spatial distribution. On the whole, the price is low in the southwest, but high in the northeast. The high-value areas are mainly concentrated in three areas: Yudai River Riverside, Xuzhou Paradise in the north, Hanwang Scenic Spot in the middle and the Panaxi Valley tourist spot in the south. Based on the principle of ecological value transformation, combining with the spatial distribution characteristics of ecological value in Hanwang town, four modes of promoting ecological value transformation were proposed: ecological industrialization management, ecological governance and value promotion, ecological resource index trading and ecotourism. This paper preliminarily explores a method to calculate and transform the value of ecological space, which provides feasible concrete strategies for the protection of ecological space and the development of ecological industry in towns.

The over-exploitation and utilization of natural resources in mining cities has caused sharp contradictions between urban development and ecological protection. In addition, dynamic changes in resources and environmental carrying capacity (RECC) will be changed by the different ways and degrees of the specific utilization of natural resources. In order to better study the dynamic trends and reasons of the RECC in mining cities, so as to provide methods and suggestions for the mining cities to save resources, improve the ecology, and adjust the industrial structure, this article will construct an evaluation index for the RECC of mining cities. Taking Huaihai Economic Zone as the research object, we used the entropy method to determine the index weight. Then, the TOPSIS model was used to analyze the spatial and temporal characteristics of the development of the RECC of mining cities in coal-concentrated areas during 2012–2018. After the analysis, the study found five results. (1) Except Zaozhuang, the RECC of the six mining cities in the Huaihai Economic Zone showed a steady upward trend during 2012–2018; (2) among the three subsystems, natural resources have the greatest impact on the RECC; (3) in terms of space, the carrying capacity in this region gradually has a polarization phenomenon centered on Xuzhou and Jining, and will continue to increase in the future; (4) the types of mining cities will have an impact on the change characteristics of the RECC; and (5) most cities improve the level of ecological carrying capacity (ECC) and social economic carrying capacity (SECC) at the cost of the decline of resources carrying capacity (RCC). Based on the results, the research can provide optimized reference strategies for the transformation and development of mining cities to ecological cities in Huaihai Economic Zone.
