Studies on Climate Potential Productivity of Dryland Farming in Fuxin of Liaoning Province

Abstract:

Based on the meteorological data for the period of 1951-2009 in Fuxin,the article estimates the photosynthesis, photo-temperature and climate potential productivity of dryland farming in Fuxin of Liaoning province, and analyzes the potential productivity interannual change in crop growth period (April-September). The result shows that the long-time average value of the photosynthesis, photo-temperature and climate potential productivity are 31.89×10⁴kg/hm², 26.80×10⁴kg/hm² and 18.29×10⁴kg/hm² in Fuxin. The interannual change trend of potential productivity is that the photosynthesis, photo-temperature and climate potential productivity are overall reduced, the photosynthesis and photo-temperature potential productivity are not obvious, and the climate potential productivity is obvious. The monthly climate potential productivity contour maps show that the climate potential productivity change dramatically, and the low evalue areas of crop growth period have the continue expansion trend after 2009.
