佛冈县域土地综合整治项目的区位选择

Location choice for integrated land consolidation project in Fogang county

为科学合理选择土地整治项目区,该文以佛冈县为例,阐述县域土地综合整治的目标和类型,并确定土地整治的主导功能,在此基础上,结合国家和地方土地整治有关政策和法规规定,确定土地整治项目点的整治类型及其潜力等级,并利用ArcGIS空间分析功能,编制了综合潜力等级图,根据县域土地综合整治项目区选择的原则和要求,利用土地整治综合潜力等级图,获取佛冈县域土地综合整治项目区构成体系。结果表明:佛冈形成了3个明显的以河流治理、农用地整理和城乡建设用地整治相结合的流域综合整治区,即潖江流域综合整治区Ⅰ、整治区Ⅱ和烟岭河综合整治区;城乡建设用地挂钩重点区位于石角镇吉田村、凤城村,迳头镇大陂村;城乡土地综合整治重点区位于龙山镇鹤田村,汤塘镇联和村、新塘村,水头镇王田村;农村土地综合整治重点区位于龙山镇车步村,汤塘镇汤塘村、围镇村、江坳村,迳头镇社坪村;农地景观综合整治的重点区位于龙山镇良塘村。该文为系统地选择区域土地整治项目区提供了参考。

The integrated land consolidation（LC） is a major engineering project, which requires huge financial support. In order to take advantage of limited funds, scientific and effective LC planning should be undertaken.However, selection of a LC project is the premise and foundation of LC planning; therefore the rational selection of the LC project zone directly affects the practical LC effect. Under the urban and rural harmonious development background, the integrated LC project zone system of a county should be structured as an organic whole in which LC projects are selected in relation to each other by the different levels and types.Taking Fogang County as an example, the paper discussed the issue that LC projects were systematically chosen within the scope of the county. First, the paper elaborated the objectives and types of the county-wide integrated LC, and proposed the dominant function of the LC. Second, the paper which combined the relevant national and local policies and regulations of the LC determined the types and integrated LC potential rank of the land block（LC project site） based on the LC functions, and formed the LC potential rank map using the function of spatial analysis of GIS. Finally, according to the selective principles and requirements of the LC project zone, a system of the integrated LC project zone in Fogang was established by the LC potential rank map. The results showed that the system of the integrated LC project zone was composed of three different levels and types of watershed remediation, multi-function LC, and single-function LC in Fogang County. That is, the Pajiang river basin Ⅰdistrict, the Pajiang river basin Ⅱ district, and the Yanling river basin district. Jitian village, Fengcheng village and Dabei village are the key region of urban and rural construction land hook. Hetian village, Lianhe village,Xintang village and Wangtian village are the key region of the integrated LC for urban and rural construction land.The key region of the rural integrated LC is Chebu village, Tangtang village, Weizhen village, Jiangao village and Sheping village. Guitian village and Jiangao village is the key region of the rural integrated LC of based rural residential LC. Liangtang Village is the key region of the integrated LC of the based environmental governance and agricultural LC.This paper argues that the integrated LC project system of the county should be built on the basis of a view of a whole region. The integrated LC general planning should be conducted based on the integrated watershed remediation project zones. The compilation of special planning can be selected according to the single and integrated LC project zones. In addition, the key LC project zones were implemented preferentially which bound together the local economy and the potential of the LC project zones. The method can both improve the systematic nature of the LC planning, and ensure the prioritized completion of key LC projects. The research can provide a reference for the systematic choice of the regional LC projects.
