摘要:
生态安全正逐渐成为国家安全体系的重要组成部分,开展生态安全评价研究,可为国家生态环境保护、生态文明建设以及人与自然永续发展提供科学依据。以北回归线(云南段)县级行政区域为研究单元,结合DPSIR模型与EES模型,重点引入了矿产开采活动影响因素,构建了北回归线(云南段)的区域生态安全评价指标体系,运用层次分析法与熵值法分别计算了各个指标的权重值,通过加权叠加开展了北回归线(云南段)生态安全评价研究。结果表明:(1)北回归线(云南段)总体生态安全状况为临界安全状态,局部生态安全状况较为脆弱,空间差异性较为明显,其中生态环境状况为安全和较安全的区域共占37.87%,主要分布于人口密度小、植被覆盖较为广泛的研究区东部和西部; 处于临界安全的区域占28.87%,整个研究区均有分布; 较不安全和不安全的区域共计占比33.26%,主要分布于研究区域中部经济发展速度较快的县市。(2)通过对生态环境安全评价结果以及主要影响因素进行叠加分析发现,主要影响生态环境安全状况的因素有大规模的矿山开采活动、地质灾害频发、耕地的大面积开垦与长期耕种、植被覆盖遭到破坏以及土地利用类型等因素。
Abstract:
Ecological security is gradually becoming an important part of the national security system. Carrying out ecological security evaluation research can provide a scientific basis for national ecological environmental protection, ecological civilization construction, and sustainable development of human and nature. Taking the county-level administrative area of the Tropic of Cancer(Yunnan section)as the research unit, combining the DPSIR model and the EES model, we constructed the regional ecological security evaluation index system of the Tropic of Cancer(Yunnan section), used the analytic hierarchy process and the entropy method to calculate each indicator separately based on the weighted value, and carried out the ecological safety evaluation research of the Tropic of Cancer(Yunnan section)through weighted superposition. The results show that:(1)the overall ecological security status of the Tropic of Cancer(Yunnan section)is critically safe, the local ecological security status is relatively fragile, and the spatial differences are more obvious, among which the areas with safe and relatively safe ecological environment status account for 37.87%, and distribute in the east and west of the study area with low population density and relatively extensive vegetation coverage, and areas with critically safe ecological environment status accounte for 28.87%, distributed throughout the study area; less safe and unsafe areas totaled 33.26%, and mainly distribute in the cities and counties in the middle of the study area where the economy is developing rapidly;(2)through the superposition analysis of the ecological environment safety assessment results and the main influencing factors, it is found that the main factors affecting the ecological environment safety are large-scale mining activities, frequent geological disasters, large-scale reclamation of cultivated land, long-term cultivation, and factors such as damage to vegetation and types of land use.
