Evaluation Research on Intensive Land Use of Modern Agricultural Park

摘要

With nearly thirty-year rapid development, contradiction of the demand of sustainable and sound development of agricultural park and limited land supply becomes especially obvious. The article takes the modern agricultural park in Pengxi County, Sichuan Province as an example. Establish the evaluation index system for intensive land use of the park. Land use intensity of Pengxi modern agricultural park from 2011 to 2015 is separately calculated to be 0.3921, 0.5152, 0.5331, 0.5627, 0.6320 by virtue of BP-neural network model. The results showed that, since the establishment of Pengxi modern agricultural park, output effect and use ratio of land in the area has reached a level of preliminarily intensive level, and the increasing state is relative stable, however, it still remains to be improved.
