In some regions in northern China drought

Xinhuanet, Beijing, January 29 (reporters Lin Hui and and Huang Yan)-since the beginning of winter last year, due to high temperatures, water scar, with varying degrees of drought in parts of China, particularly as represented by the winter wheat growing areas in the North.

Figures from China's national headquarters, as of January 27, national drought-stricken area of 20.81 million acres of winter crops, 470,000 people because of drought of drinking water, small figures are higher mean value over a year earlier, but the situation cannot be ignored.

National Headquarters informed the official website of current drought conditions. Current drought mainly occurred in Henan, Gansu, Hebei, Shanxi, Shaanxi Province, and presented four distinctive features: severe low precipitation. Winter wheat growing areas in the North lower winter precipitation over a year earlier to 30%-50%, 60-80 days, no effective rainfall in most areas, Shaanxi, Shanxi, Hebei, Henan, Shandong and Beijing with an average rainfall of 0. 3 mm, representing annual low of 97%, as historical is worth at least the same period since meteorological records began in 1950.

Drought-resistant water sources are insufficient. Rivers in Huang-Huai-Hai area water scar, lower middle reaches of the Yellow River to water 40%-50%, small upper and middle reaches of the huaihe River and the haihe River Juma River 70%. Lack of water in some areas, small medium and large reservoir in Gansu province over a year earlier to 10%, Shaanxi Province, lower part of the small and medium sized reservoir throughout the period of nearly 40%.

Soil moisture content was poor. Henan, Gansu, Shaanxi and Shanxi province winter wheat region table insufficient moisture, weibei, Shaanxi Province, Guanzhong and shangluo local soil moisture poor, most of moisture a serious loss of cultivated land in Hexi region of Gansu province.

Drinking water difficulty highlighted. Low precipitation led to some heavy dry streams dried up, the well dried up, cellar sudden lack of water storage capacity, coupled with the Chinese new year will come home staff increased, some areas drinking water. Among them, the cellar half water shortage one-third the eyes of 1.36 million in Gansu province, some people drinking water rely on far-distance water.

It is predicted that rainfall may be less 40%-50% of winter wheat region this spring, as temperatures rise, the crop into turning green season, spring plowing production and irrigation water shortage is more serious the drought situation is grim.

The Yangtze River flood control Headquarters said, will strengthen the scientific control of three Gorges reservoir, respond in a timely manner within the catchment have been drought conditions, give full play to comprehensive benefits of large water conservancy project.

　　新华网北京1月29日电（记者林晖、黄艳）去年入冬以来，由于气温偏高，来水偏枯，中国部分地区出现不同程度旱情，尤其以北方冬麦区为代表。

　　来自中国国家防总的数据显示，截至1月27日，全国越冬作物受旱面积2081万亩，有47万人因旱饮水困难，数字均较多年同期均值偏少，但形势严峻不可忽视。

　　国家防总官网通报了当前的旱情。目前旱情主要发生在河南、甘肃、河北、山西、陕西等省，并呈现四个明显特征：降水严重偏少。北方冬麦区入冬以来降水量较常年同期偏少三至五成，大部分地区60至80天无有效降雨，陕西、山西、河北、河南、山东及京津地区平均降水量0．3毫米，较常年同期偏少97％，为1950年有气象记录以来历史同期最少值。

　　抗旱水源不足。黄淮海地区江河来水偏枯，黄河中游来水偏少四至五成，淮河上中游和海河拒马河偏少7成。部分地区蓄水不足，甘肃省大中型水库蓄水较去年同期偏少10％，陕西省部分中小型水库蓄水比常年同期偏少近四成。

　　土壤墒情较差。河南、甘肃、陕西、山西等省冬麦区大部表墒不足，陕西省渭北、关中和商洛局部地区底墒较差，甘肃省河西地区大部分耕地失墒严重。

　　人饮困难突出。降水偏少导致部分重旱区溪流干枯、泉井干涸，水窖蓄水量锐减，加之春节将至返乡人员增多，一些地区群众饮水困难。其中，甘肃省136万眼水窖有一半蓄水不足三分之一，部分百姓饮水靠远距离拉水。

　　据预测，今年春季冬麦区降雨可能偏少四至五成，随着气温回升，作物进入返青季节，春耕生产全面开展，灌溉水源紧缺的矛盾将更加突出，旱情形势严峻。

　　长江防总表示，将加强三峡水库的科学调度，及时应对流域内已经出现旱情，充分发挥大型水利枢纽的综合效益。
