Evaluation And Analysis Of The Pressure Of Cultivated Land In Kunming City

The purpose of this paper is to study current situation of cultivated land pressure inKunming, analyze the influence factors of cultivated land pressure, and then putforward the measures for sustainable utilization of cultivated land. Study areaincluding panlong,Wuhua, Guandu, Xishan, Chenggong5districts of Kunming cityand Dongchuan, Jinning,Fumin, Yiliang, Songming, Shilin, luquan, Xundian eightcounties and Anning a city. The paper ues the model of minimum area of per capitacultivated land and cultivated land pressure index which Cai yunlong created,analyzing Kunming population, arable land, cultivated land area, crop planting area,ect, the basic data in2010,then we get the spatial distribution pattern of cultivated landpressure index of each region in Kunming.Analysis results show that the spatialdistribution of cultivated land pressure is very significant difference in different area,Kunming city and Chenggong cultivated land pressure is the largest of the studyarea,other areas of cultivated land pressure are much smaller than the two regions. Byanalyzing various factors affecting food production and food demand, indicates that theresults accord with the actual situation of Kunming area of cultivated land, canobjectively reflect the actual situation of Kunming area of cultivated land pressure.
