气候变暖对黑龙江省水稻发展的影响及其对策的研究

The Effect of Climate Warm -up for the Development of Rice in Hei Longjiang Province and the Str ategy Studies

80年代气候变暖使黑龙江省热量明显增加,尤其黑龙江、松花江、乌苏里江流域热量增加明显。气候变暖使三江平原东北部降水有不同程度的增加。分析全省地表径流、旱涝区划,提出了水稻发展的最佳种植区。并根据目前水资源和最大供水量状况,预测了黑龙江省2010年发展水稻种植面积为2000年的160%,进而指出发展水稻种植的重点应放在黑龙江下游、挠力河与乌苏里江之间。

Climate warm -up in 1980' s,which caused the increasing of hea t in Hei Longjiang province,especia lly in the valleys of Hei Long river Song Hua river and Wu Suli river,the heat increased obvio usly.Climate warm -up also caused th e increasing of precipitation to a certain extent around the area of three rivers plains.The most suitable place for growing r ice was put forward through the analysis of the runoff in the ground and the classification of drought and waterlogging.And according to the water re-source and the water provided situation,we predicted that the rice growi ng area in 2010would be 160%of that in2000.And concluded that the most important pl ace for growing rice should be at the l ower reaches of Hei Long river and the area between the Rao Li river and Wu Suli river.
