The Spatial Pressure Distribution of Cultivated Land and the Analysis of Food Safety in Kunming City

PENG Er-rui et al (Faculty of Water Conservancy,Hydrolic Power and Architecture,YAU,Kunming,Yunan 650201)  
Taking the minimum average per capita cultivated land and exponent modal of cultivated land pressure,according to the data of culti-vated land,the crop yield and population,comparing the different average per capita need for food,the comparative research method was used to calculate and analyze the minimum average per capita cultivated land and exponent modal of cultivated land pressure. Combining the spatial distribution characteristics of the cultivated land and food with the situation of industrial development,the countermeasures and suggestions were put forwarded to make full use of back up cultivated land,to plan the industrial make-up in as a whole,to dispose cultivated land resources reasonably,to increase the average per capita need for food,to lighten the cultivated land pressure,to promote the utilization ratio of cultivated land and to ensure food safety.
