【摘要】：[目的]农村居民点优化对耕地保护及农村建设用地集约利用具有重要意义。[方法]借助高分辨率卫星影像和GIS手段准确提取研究区村庄实际占地,以生态敏感性分析为基础,以建设用地适宜性评价为手段对屯昌县农村居民点用地现状进行评估,按照生态敏感性评价结果和建设用地适宜性由低到高的顺序决定农村居民点用地整治的区域。[结果]研究表明:(1)位于生态极敏感、高度敏感、中度敏感、轻度敏感、和不敏感区域的村庄面积分别为0.04hm~2、2.41hm~2、42.10hm~2、835.93hm~2和2 990.21hm~2。(2)位于禁建区、限建区、次级宜建区和优先建设区的现状村庄面积分别为46.42hm~2、501.91hm~2、2 423.23hm~2和864.76hm~2。(3)全县农村居民点理论优化面积为547.76hm~2。其中,优化区域主要集中于中部"类盆地"区域,优化区域面积位居前三位的镇分别为乌坡镇、南坤镇及屯城镇,优化面积分别为108.49hm~2、107.07hm~2和103.30hm~2,面积最小的为枫木镇,仅为34.96hm~2。[结论]综合分析研究结果可知,针对不同生态敏感性和不同用地适宜性的区域应该采取不同的土地利用方式。
[Abstract]:[objective] the optimization of rural settlements is of great significance to the protection of cultivated land and intensive utilization of rural construction land. [methods] the actual land occupation of villages in the study area is accurately extracted by means of high-resolution satellite images and GIS, and based on ecological sensitivity analysis. The present situation of rural residential land in Tunchang County was evaluated by means of suitability evaluation of construction land. According to the results of ecological sensitivity evaluation and the order of suitability of construction land from low to high, the area of rural residential land reclamation is determined. [results] the study shows that: 1) is located in ecologically extremely sensitive, highly sensitive, moderately sensitive and mildly sensitive. The village area of the insensitive area is 0.04hman2hmzhuan2hmzhuan42.10hmcmc2hmf2 and 29990.21hmmmf2). The current village area of the restricted area, the restricted area, the secondary suitable area and the priority construction area are 46.42hmmmt2501.91hmtmtou and 864.76hmmfen, respectively. The theoretical optimum area of the rural residential area in the whole county is 547.76hmf2, respectively, and the area of the current village area is 46.42hmzhuan2501.91hmzhuanzao and 864.76hmmmf2. 3) the optimum area of the rural residential area in the whole county is 547.76hmcmmmnmng2, respectively. The optimized area is mainly concentrated in the "basin of the type" region in the middle. The top three towns are Wupo Town, Nankun Town and Tun Town respectively. The optimized areas are 108.49hmP2107.07hmmt2 and 103.30hmmf2, respectively, and the area of Fengmu Town is the smallest. [conclusion] Comprehensive analysis results show that different land use methods should be adopted for different ecological sensitivity and land suitability.
