Study on the spatial variation of China’s territorial ecological space based on the standard deviation ellipse

With the rapid development of China’s economy and acceleration urbanization, expansion urban space has led to a growing demand for land that resulted in destruction expropriation large amount ecological China. In face current situation resource constraints, environmental degradation, ecosystem destruction, it is necessary thoroughly study territorial China its evolution rules. Based on previous studies classification use, this proposes concept distinguishes from agricultural space. A matching system been established, which may help understanding model related processes. According constructed system, spatial data processing was conducted. The standard deviation ellipse used analyze pattern various spaces migration their barycenter. results show following: 1) area showed downward trend 2000 2015. From aspect flow, mainly flows into space, followed by division first-level main structure grassland woodland 2) distribution characteristics are more prominent, very uneven. During period, variation angle ? small, barycenter not obvious, indicating relatively stable state. 3) It implement differentiated policy optimization control according non-equilibrium build unified coordinated management system. Such differentiation would provide basis decision making reference formulating strategies sustainable regional environment optimizing layout territory.
