Study on Exploitation Potential Evaluation of Reserved Land Resources Suitable for Cultivation in Wuhua County of Guangdong Province

Abstract

The exploitation potential evaluation of reserved land resources suitable for cultivation is a scientific basis to conduct the land development and consolidation. Combining with the actual situation of Wuhua county of Guangdong province, based on the suitable evaluation for cultivation, this paper selects five evaluation factors from the perspective of project implementation such as the terrain slope, the road density, the irrigation condition of surrounding farmland, the nearest distance to farmland and the map spot area of the nearest farmland to build the evaluation index system, and evaluate the exploitation potential of the reserved land resources. According to the area of supplementary cultivated land and the grading unit of the administrative village, the exploitation potential of the reserved land resources in Wuhua is divided into three partitions. The evaluation results show that the exploitation potential of Wuhua county is 731 hectares under the productivity level of present and foreseeable period, including other grassland, inland beach and bare land, mainly distributed in the basin and river valley of midland. The potential grading results show that the potential area of gradeIis 586.54 hectares, which terrain is flat and given the first priority to exploitation; the potential area of gradeIIis 128.84 hectares, which distribution is scattered and is given the second priority to exploitation; the potential area of grade III is 15.62 hectares, which mainly distributed in mountainous region and could be alternative to exploitation. The research results can provide a reference for development and arrangement planning of reserve land resources in Wuhua county.
