Discovery and prediction of the unused land for construction based on random forest

摘要

With the rapid development of the society of China, a large number of land problems such as unused land or inefficient used land for construction exist in the process of land usages, which leads to a waste of massive land resources. In the management of land resources, not only solving the existing problems of the land, but also prediction of the problems of the land and prevention on land abuse are in demand urgently of the urbanization. In this paper, based on the land data of different time of Hannan district in Wuhan City, the algorithm of Random Forest is used to analyze and predict the problem of unused land for construction. The results show that with more related features of land problems, the algorithm of Random Forest has good performance on the unused land discovery and prediction.
