影响和田冬季设施农业的气候变化特征分析

利用和田地区1961—2006年4个代表站的气候资料,对设施农业主要生产阶段冬季(12月—次年2月)的平均最低气温、浮尘日数、降雪日数、日照时数等气候因子的变化特点进行分析,结果表明:平均最低气温上升,日照时数增加,浮尘日数下降,上述变化对设施农业生产是有利的;但是降雪日数增加,对设施农业生产不利。针对和田地区气候特征,在加大设施农业发展力度,建立南疆特色瓜果蔬菜基地的同时,需要加强雪灾、冷害防御措施。

The Analysis on the Climate Change Characteristics of Influencing Winter Installation Agriculture in Hetian

Used the climate data of four representative stations in Hetian area from 1961 to 2006,analyzed the changes characteristic of climate restriction factor such as mean minimum air temperature,dusts days,snow days and sunlight hours in main production period of installation agriculture(Dec.to next Feb.),the results showed that the mean minimum air temperature,the sunlight hours present up-trend and the dusts days presents down-trend,these are beneficial to installation agriculture;at the same time the snow days presents up-trend which is harmful to installation agriculture.According to the climate characteristic of Hetian area,we should increase the strength of installation agriculture development,establish the base of the characteristic melons,fruits and vegetables production in southern Xinjiang,and strengthen the measures to avoid cold harm to enhance the quality.
