土地开发潜力测算——以哈巴河县为例

开展合理的土地开发潜力评价,增加有效耕地面积,是当前土地整治迫切需要解决的问题。本文构建了土地开发潜力评价模型,从土地利用现状、自然因素、社会经济条件以及生态因素四个方面选取了12个指标构建了土地开发潜力评价指标体系。选取了具有代表性的新疆哈巴河县作为研究区,以县域行政村作为主要评价单元,应用GIS方法开展了实证研究。结果表明：哈巴河县未利用土地开发潜力大,但限制因素如坡度、水源、土壤质地等较多,近期开发难度大。县域可划分为高、中、一般、低四种不同潜力区,土地开发宜优先在中高潜力区开展,低潜力区则应加强生态环境保护,因地制宜发展畜牧业。

The potential measurement for land development -A case of Habahe County

Objective] To carry out reasonable potential evaluation of land development and increase the effective arable land area is a currently urgent need to solve the problem of land consolidation.Method]Potential evaluation model of land development was proposed and potential evaluation index system of land development was constructed from land use, natural factors, socio-economic conditions and ecological factors of 4 aspects 12 indicators. By selecting a representative case, Habahe County, located in the Xinjiang Uygur Autonomous Region, the administrative villages in Habahe County were put as main evaluation units and GIS method was applied to conduct empirical research. Result]The results indicates that unused land development potential is high with limiting factors such as slope, water, soil texture , so the recent land development is difficult. Conclusion] It shows that 1) Hahahe County can be divided into high, medium, general and low potential partitions, 2) high and medium potential partitions are the priority land development area , 3)With positive ecological environment protection,animal husbandry should be developed in low potential partitions to adapt the local conditions.
