Suitability Evaluation and Zoning of Construction Land for Suburban Villages and Towns Based on ESP and MCE Model: A Case Study in Qunfeng Town, Zhuzhou City, China

Abstract

As a result of the booming city development in china, the recurring problem of “overdevelopment and ecosystem damage” reflects the inadequate understanding of sustainable environment. The suitability evaluation and zoning of construction land in suburban villages and towns is an important way to guide the coordinated development of space expansion and ecological environment protection. To better understand the suitable uses and the development direction of land based on the security protection of ecology. This study proposes a method of suitability evaluation and zoning based on the model of minimum cumulative resistance (MCR) and ecological security pattern (ESP). First, ecological security pattern shows a stepped spatial trend, and the high-level area accounts for a large proportion, in which traffic location and land use mode are the key factors; Second, the most suitable and suitable types of construction land account for more than 1/2 of the total area, with obvious advantages in economic activities; Third, the gap of 0.52km2 protection gap is identified, indicating that there is a spatial conflict between land development and ecological security; Finally, there are three types of zoning based on the suitability evaluation: Economic development zone, Agricultural safety zone and Ecological safety zone. This study indicates that the suitability and zoning of construction land can effectively optimize and regulate the spatial governance of land use, and provide a theoretical basis for the preparation of land spatial planning of suburban villages and towns.
