Evolution of Green Space Based on Remote Sensing Images in Zhengdong New District

Abstract

With the continuous advancement of urbanization, the socioeconomic development and environmental damage in Zhengdong New District of Zhengzhou City seriously threaten the development of green space. The paper focused on Zhengdong New District and selected four important nodes in 2007, 2011, 2015, and 2019 to interpret the remote sensing image, explore the local spatial evolution through the method of land use transfer model construction, extract the green space area conversion analysis information of the study area, and analyze the influence factors of its transformation. The research shows that from 2007 to 2019, the internal structure of green space in Zhengdong New District that were cultivated land, woodland, grassland, and water bodies, its showed different trends, and the dynamic changes were different. Among them, the area of cultivated land continued to decrease, the area of construction land continued to increase, the total area of woodland increased, the area of grassland and water bodies fluctuated, and the total green space was greatly reduced; the conversion of land types in Zhengdong New District mainly focused on the conversion of cultivated land to construction land, woodland, and grassland. The results shows that the green space of Zhengdong New District is affected by social, economic, natural, and other factors and various factors interact with each other. However, social and economic development factors are obviously stronger than natural and administrative factors on the evolution of green space area.
