摘要
研究目的:探寻生态脆弱山区农村居民点整治适宜性评价方法,使山区农村居民点整治产生较大社会效益、经济效益的同时创造更大的生态效益。研究方法:根据"源""汇"景观理论,建立针对农村居民点整治的景观空间负荷对比指数评价模型。研究结果:以十堰市房县为研究区开展适宜性评价,沙河乡、万峪河乡等7个乡镇的景观空间负荷综合对比指数为0.96、0.92等,较适宜开展农村居民点整治;土城镇和化龙堰镇不同级别的指数出现急剧增加后波动较小,也较适宜开展农村居民点整治。最后对整治适宜性进行验证,评价结果与已开展整治的情况高度吻合。研究结论:构建的农村居民点整治适宜性评价方法具有可行性,可为生态脆弱山区农村居民点整治提供决策依据。
The purpose of this paper is to develop an evaluation method of suitability of rural residential land consolidation in the ecologically fragile mountainous region to make the rural residential land consolidation generate greater social and economic benefits while creating greater ecological benefits.Based on the “Source-Sink” landscape theory,the model of location-weighted landscape contrast index (LCI) was established for the rural residential land consolidation.Taking Fang County of Shiyan City as an example to evaluate the suitability of rural residential consolidation,the results show that:LCIs of seven towns such as Shahe town and Wan Yuhe town,are 0.96 and 0.92,etc,which are more suitable for rural residential consolidation;LCIs of Tucheng town and Hua Longyan town change slightly after the sharp increase,which are also suitable to develop the rural residential land consolidation.At last,the area of the evaluation unit where carried out rural residential land consolidation and the size of LCIs are compared to verify the suitability,and the evaluation result is in consistence with the situation of the consolidation.In conclusion,the evaluation of the suitability of rural residential land consolidation is feasible and can serve as the decision-basis for rural residential land consolidation of the ecologically fragile mountainous region.
