The Spatial Analysis of Population Pressure on the Ecological Environment in China during 1990-2010 Years

Abstract

This paper examines the temporal and spatial variations of population pressure on the ecological environment in China. We have collected sufficient data from the statistical yearbooks of 31 provincial administrative areas in 1990, 1995, 2000, 2005 and 2010. By using the geographic information system (GIS) and relevant models, we analyzed the trend of the population pressure on ecological environment. We conclude that: 1) generally, population pressure on the ecological environment in China was becoming higher, especially in some areas, the population and environment was in severe imbalance and the ecological environment experienced serious pollution; 2) during a certain period when population pressure on the ecological environment was becoming lower in some areas, the ecological environment was getting worse; and 3) the areas of super high population pressure on the ecological environment were Beijing, Tianjin and Shanghai.
