Evaluation of ecological security of land resources in Nanning City
摘要
Abstract
[Objective]Ecological security of land resources was evaluated and its strategies were proposed to maintain sustainable utilization of regional land resources. [ Method ]The multi-index comprehensive evaluation method was adopted to calculate the level of ecological security of land resources. [Result] With large population density and insufficient infrastructure, Nanning City was found to be at risks. Its ecological environment was further deteriorated by rapidly-growing population and dramatically decreasing land per capita- Long'an, Mashan and Hengxian were at sensitive level of ecological security, and their land utilization, environmental protection, economical and social developments were developing moderately. Wuming, Shanglin and Binyang County showed better level of ecological security with reasonable land structure, good food stuif supply, environmental protection and ecological construction. [Suggestion]Ecological security of land resources in Nanning City can be secured through planning land ecology, regulating ecology protection, controlling city scale, strengthening land utilization, reinforcing people's awareness on ecological security, strictly implementing land policies, safeguarding ecological land, keeping population at a rational level, and improving population quality.关键词
