A Study on Land Utilization Decision Making Based on WNN Model
2013, 28 (8):
The purpose of this paper is to discuss the land utilization decision making based on WNN model in the three needs of agricultural production, construction and development, and ecological protection, which can provide references for sustainable use of land resources and ensuring the coordinated development with economic benefits, social benefits and ecological benefits. Method of wavelet neural network (WNN) model was employed. The results indicate that the WNN model of land utilization was built by using the data of the Second National Land Survey in Yuzhong basin, which has obtained different types of land utilization in the three needs: 1) in agricultural production needs, Jinya is in a semi-intensive used state, Chengguan, Xiaguanying, Dingyuan and Xiaogangying are in a semi-extensive used state, and Heping and Lianda are in an extensive used state. The land input-output ratio in the agricultural production needs is uncoordinated. 2) Land utilization type for the construction and development needs in Yuzhong basin is in an extensive transition used state. Jinya is in a semi-intensive used state, Heping, Dingyuan and Lianda are in a semi-extensive used state, Chengguan and Xiaguanying are in an extensive used state. A good proportion of the land input-output in the construction and development needs hasn’t been achieved. 3) In ecological protection needs, land utilization in Yuzhong basin is in a semi-extensive and extensive used state. Heping, Dingyuan, Lianda and Jinya are in a semi-extensive used state, meanwhile, Chengguan and Xiaguanying are in an extensive transition used state. The conclusions are as follows: 1)the needs of different conditions and efficiency must be considered in the study of land utilization decision making. And then, decision-making analysis is made for different land use types for achieving the optimal allocation and sustainable use of land resources, improving land use and management level, and ensuring the coordinated development with economic benefits, social benefits and ecological benefits; 2) WNN model is more scientific and operational to the study of land utilization decision making.
