Title: Analysis on Pressure Index of Cultivated Land and Its Predictionin Xinyang
Abstract: By the dynamic analysis of the cropland pressure index of Xinyang in 2003-2012,it is found that the pressure index maintains stability after falling trend.This indicates the grain production is in a relatively safe state in Xinyang.This paper predicted the development of the area of per capita cultivated land,the grain yield and other factors influenced the farmland pressure index of Xinyang by using Grey Theory GM(1,1)model,and on this basis calculated the change of Xinyang cultivated land pressure index in the future.Finally,we put forward some specific policy recommendations for cultivated land protection like increasing the input of agricultural scientific research,to guide farmers to fully develop non-cultivated land and unused land resources.
