气候变化对青海省种植业的影响及适应对策

Impact of Climate Change on Cropping Systems and Adaptive Strategies in Qinghai Province

从青海省种植业存在结构单一、为畜牧业提供的饲草 (料 )有限、春播作物收获后的水热资源没有充分利用等现状出发 ,结合青海省未来气候暖干化的发展趋势 ,提出了青海省种植业结构调整对策 :如实行农区兴林、旱区兴牧 ;利用春播作物收获后的余热资源提高复种指数 ;利用冬、春季增温明显的气候特点扩大冬小麦的种植面积等。

Under the background of global warming, the rational exploitation and utilization of the climate resources, the water and heat configuration, reduction of the expected reverse impacts and vulnerability to climate change on agriculture were analyzed.Based on the analysis of the unique structure of cropping system, limited forage for animal production, and no full utilization of the water and heat resources after harvest of spring crops and hot and dry tendency of future climate change, the adaptive strategies to climate change on adjusting cropping system were put forward, such as implementation of forestation in agricultural area and raising stock in the arid areas, raising multiple cropping index and expanding planting area of winter wheat.
