Optimization Method for Green Infrastructure in Hanwang Town in the Context of the Integration of Agriculture and Tourism.

As an important measure for maintaining the ecological environment, green infrastructure also plays a significant role in industrial development and economic growth. The current traditional green infrastructure construction method is based on a combination of vertical and horizontal ecological processes, but it does not take into account the complexity of the ecosystem or the motivating effect of green infrastructure on industry. This study investigated how green infrastructure can play the leading role in industry while considering the complexity of the ecosystem. Hanwang Town is the most representative village and town in China with the leading agricultural tour-industry, and it is located in the northern part of Jiangsu Province. However, the ecological security patterns of villages and towns have been severely damaged in recent years, and the green infrastructure has not played a role in industry. Therefore, taking Hanwang Town as the research area, the data of the third national survey were combined with relevant statistical data. Then, from the perspective of the agriculture and tourism industries, ecosystem services were used as a bridge to improve the recent green infrastructure construction methods, and finally better strategies are proposed according to the optimization results. The research results revealed three important aspects of this system. (1) The optimization method can comprehensively consider the impact of environmental factors, objectively reflect the value of ecological services in the form of currency, reflect the importance of environmental protection with intuitive values，and enhance people's awareness of ecological protection. (2) The selection of ecological factors takes into account the local characteristic industries of Hanwang villages and towns, and adding the appropriate industry-related ecological factors makes the identification of ecological sources based on ecosystem services more scientific, and can also bring benefits to the local residents. (3) The newly constructed green infrastructure fully takes into account the landscape, ecology, tourism and other roles played by tourist attractions on the ecological corridor. There are six tourist attractions in the selected ecological nodes, forming an ecological network space with an agglomeration economic function, and this allows the ecological service function to better integrated. The findings of this research can effectively solve the shortcomings of the traditional green infrastructure construction methods, and reveal optimization strategies for the problems existing in the current green infrastructure construction in Hanwang Town. At the same time, they can also provide a reference for the green infrastructure construction of agricultural and eco-tourism villages and towns in other regions. [ABSTRACT FROM AUTHOR]
