气候变化对我国农业影响的研究进展

The World Climate Changes to Affect to Agriculture

综述了全球气候变化对我国农业的影响。气候变化直接影响农业湿地作物产量,使水稻产量减少;CO2浓度的增加既有利于作物生长,又会抑制利于作物生长的其他因素;紫外线增多直接使作物产量降低、蛋白质和脂肪减少;气候变暖会影响我国的农业气候条件和种植制度、作物品种的布局、产量、施肥水平;气候变暖将使江河水量、水资源的供需状况、旱涝灾害出现的频率、水质等发生变化,从而影响农业。

The article checked a large quantity of date and tally up the influnce of the world weather to our country＇s agriculture. The direct influnce of weather change is that it will have effeet on wet farm crop yield and decrease the paddy rice yield. The increase of C02, on one hand well promote the growth of crops, on the other hand will reposes other factors that help. The increase of Ultraviolet Ray will cut down the yield as well as the percentage of protein and fat. Warming weather will effect our country＇s agriculture weather and plant term, layout of the crops, yield fertilizing. Also, the change of the climate will change the amount of water in rivers and lakes, change the water resou^es, effect the frequncy of flood and drought as well as water quality. And all that have effects on agriculture.
