Accurate Prediction of Rural Construction Land Consolidation Potential and Identification of Land Consolidation Priority
The purpose of this study is to estimate the consolidation potential and accurately identify the priority of land consolidation in different villages,to make the consolidation decisions more accurate and scientific.The research methods are as follows.Firstly,Huangmei County in Hubei Province is taken as the research object,and the villages are classified according to spatial planning and their own characteristics.Then,for each type of village,the consolidation potential of rural construction land is measured.Next,one class support vector machine(OCSVM)is applied to model and identify the importance of land patch to finally arrange the consolidation priority for these potential sites that meet the constraints of total potential.The results are shown as follows.1)Five types of villages are identified,including suburban integration type,characteristic protection type,cluster development type,survival and upgrading type,relocation and merger type.The dominant village type is survival and upgrading type,with a total of 272 administrative villages.2)According to the planning,the theoretical potential of rural construction land consolidation in Huangmei County is 6 624.66 hm2,and the actual potential is 3 586.03 hm2.3)The most urgent and sub-urgent consolidation spots account for 7.21%and 15.02%of the total potential spots,respectively,while the general urgent consolidation spots accounts for 51.14%of the total potential spots.The remaining(i.e.non-urgent consolidation spots)accounts for 26.63%.In conclusion,the simulation of the potential and priority identification of rural construction land consolidation based on village classification can provide the theoretical reference and practical operation modes for village layout improvement and overall land consolidation.
