Optimization and Reconstruction of Town and Village Ecological Security Pattern under the Background of Sponge City

Abstract

Guided by the principles of landscape ecology, taking the area of 50hm2 of a Town, as an example, four ecological control factors including cultivated land area, climate hydrology, topography and geomorphology and biodiversity are selected to analyze the characteristics of the ecological pattern under the guidance of each factor. With the expansion of the scale of town and village economy, population scale and land use scale, the situation of ecological security is not optimistic, which is mainly manifested in the shortage of water resources caused by water pollution, serious pollution of river water body, the single ecological landscape system, the lack of biodiversity and so on. The construction and optimization of water security and landscape ecological security pattern can solve the governance and optimization of water pollution and landscape environment, and meanwhile, we need to adapt to local conditions to develop the local dominant industry in order to synchronize ecological construction with ecological security. The optimization and construction of town and village ecological security pattern is a systematic project. We need to take the whole situation into account from point to surface, and provide some reference experience for the optimization and construction of rural ecological security pattern under the background of new-type urbanization. The research and construction of the ecological security pattern is the foundation of making a good plan for the new countryside and promoting the sound development of the town and village.
