Embodiment Construction
[0032] The purpose and effects of the present invention will become more apparent by referring to the accompanying drawings in detail of the present invention.
[0033] Such as figure 1 As shown, it is a flow chart of the village land reclamation planning method based on the support vector machine of the present invention. Specifically include the following steps:
[0034] Step 1. Obtain the recent village land reclamation planning cases in the study area and the village land information to be planned at this stage. First of all, the research area should be established, and the research area should include two types of village lands that have made reclamation planning and reclamation planning. The specific reclamation plan refers to land demolition or land reservation, and the villages that have made reclamation plans refer to the two types of villages: land demolition and land reservation. In this step, the land use information of different types of villages in the researc...

The invention relates to a village land reclamation planning method based on a support vector machine. The method comprises the following steps: obtaining village land information of a study area to be subjected to reclamation planning; establishing a space and attribute database of village land in the study area; carrying out quantification and storage on environment variables related to reclamation planning; carrying out quantitative processing on the attribute data of the village land; replacing the reclamation planning results with numerical values and adding the numerical values to the database; carrying out numerical analysis through a support vector machine method and obtaining classification basis; and carrying out classification on the study area based on the classification basisand obtaining a planning result. The method can carry out scientific and reasonable classification on multi-element reclamation planning affecting factors, compromise non-significant interaction between the affecting factors and reduce influence of subjective factors as far as possible, and can give a large-range village land reclamation planning scheme to guide reasonable decision in the land reclamation planning process and to enable reclamation benefits and efficiency to be improved obviously.
Description
technical field [0001] The invention relates to a village land reclamation planning method based on a Support Vector Machine (Support Vector Machine, SVM), belonging to the field of land use planning. Background technique [0002] With the acceleration of industrialization and urbanization, urban state-owned land has been unable to meet the land demand for urban construction and expansion. At the same time, in order to effectively control the amount of cultivated land occupied by new construction land, a large amount of rural collective land around cities has been expropriated by local governments and converted into state-owned land. The land resources required for economic development are very limited, and the contradiction between supply and demand of land characterized by the shortage of land for urban construction has increasingly become the bottleneck of urbanization and industrialization. Through on-the-spot investigation, it is found that the phenomenon of hollow vil...
