【摘要】：区域生态安全格局对于区域经济社会可持续发展具有重要意义,浑善达克沙漠化防治作为维护防风固沙功能的重要区域,保障其生态安全尤为重要。通过对沙漠化过程的影响因素分析,构建基于植物生长、土地覆被类型、土壤侵蚀的沙漠化防治区生态安全评价指标体系,利用遥感和GIS技术分别得出各项指标评价结果,在此基础上将各要素进行叠加,得到区域生态安全状况。结果表明:"较不安全"地区占总区域面积的35.42%,"不安全"和"极不安全"地区分别占总区域面积的3.42%和0.05%。2000—2008年,浑善达克沙漠化防治区的南部与东部部分地区由自然景观转变为耕地,占总区域面积的1.19%。在浑善达克沙漠化防治区生态安全评价的基础上,结合经济社会发展压力分析,提出区域生态安全保障对策。
[Abstract]:The regional pattern for ecological security is of great significance for the sustainable development of regional economy, Hunshandake desertification prevention and control as an important region for maintenance of windbreak, safeguard the ecological security is particularly important. The influence factors on desertification process analysis, based on plant growth, land cover types, soil erosion, desertification prevention and control of ecological security area evaluation index system, using remote sensing and GIS technology were used to obtain the evaluation results of the index, the elements on the basis of superposition, get the regional ecological security situation. The results show that the relatively unsafe area of the total area of 35.42%, "safe" and "unsafe" area respectively of the total area 3.42% and 0.05%.2000 - 2008, Hunshandak Aeolian Desertification Area in southern and eastern parts of transition from the natural landscape of arable land, the total area of 1.19%. On the basis of the ecological security evaluation of the Hun DAQ desertification control area, and combining the economic and social development pressure analysis, the Countermeasures of regional ecological security guarantee are put forward.
