分析了和田附近地区近 40年气候生产力变化特征以及气候变化对农业生产的影响。重点对近 10年气温、降水与小麦、玉米产量形成的关系进行了研究 ,结果表明 2～ 4月的气温和 7～ 9月的气温分别与小麦和玉米产量有较密切的关系。同时 ,发现小麦的主要气象灾害是 2～ 4月的倒春寒 ,玉米的主要气象灾害是 7～ 9月的低温冷害
The characteristics of climatic productivity changes in the past 40 years and the impacts of climate change on agricultural production were analyzed. The relationship between temperature, precipitation and the formation of wheat and maize in recent ten years was mainly studied. The results show that the air temperature from February to April and the temperature from July to September are closely related to the yield of wheat and maize respectively. At the same time, it was found that the main meteorological disasters of wheat are from late April to late April, and the main weather disaster of maize is from July to September
