Title: Evaluation on comprehensive exploitation suitability of low-slope hilly land based on GRNN model and neighborhood calculation: A case study of Wumeng Mountain continuous poverty-stricken region
Abstract: Land is one of the most important natural resources. The exploitation of low-slope hilly land could provide the basic resource and support for industrial development in areas of land shortage. Evaluation on the land exploitation suitability is the fundamental work of planning and utilizing low-slope hilly land. It focuses on the types and grades of unused land in a region. After redefining the range of low-slope hilly land according to the physical features of Wumeng Mountain continuous poverty-stricken region, the article selected suitability evaluation indicators of arable and constructive land exploitation and then built the index system. The GRNN model was used to evaluate the grades of land exploitation suitability. What's more, it placed emphasis on the scale benefit of contiguous land exploitation and evaluated the comprehensive exploitation suitability of low-slope hilly land using neighborhood calculation. The results showed that it is of great potential to exploit low-slope hilly land in the study area. There are 313,700 and 38,400 hectares of land to be exploited as arable and construction lands respectively. However, up to 17,900 hectares of land are suitable for more purposes than one. Based on the principle of scale benefit and taking the adjacency relation with current land use and exploitation into account, it is believed that 8,400 hectares of land are more suitable to be arable land, 6,900 hectares to be construction land and 2,600 hectares not to be exploited due to the spatial isolation. Evaluation of comprehensive exploitation suitability determined that 276,800 and 22,100 hectares of land could be exploited to be arable and construction lands. The results could be significant guidance for comprehensive exploitation of low-slope hilly land in Wumeng Mountain region.
