Abstract:

It had been a new problem for agriculture to reply climate changing effect on planting structure. Based on data of meteorological observation in 1961 to 2006 and agricultural statistics (from 1949 to 2006) of five main crops(wheat, naked oats, buckwheat, potato and oil crop) at Wuchuang county in Inner Mongolia, characteristics of grain-production responding to climate effect were analyzed with method of canonical correlation analysis. Climate warming was critical in climate changing, and it was advantageous to production of potato and oil crop，disadvantageous for naked oats and buckwheat. Based on this, linear programming model had been built up according to crop yields and planting area dynamic in 2000 to 2006. Planting proportion of optimized for five crops was “wheat︰naked oats︰buckwheat︰potato︰oil crop = 1.1616︰0.4359︰0.1930︰4.7513︰3.4582” . Planting structure had being programmed was good at supply to both needs of market and resident life, and could adapted to climate warming for good utilization on climate resources.
