冬前深耘断根可增加中、下层根系的重量和比率，降低根系生长冗余性，控制最高总茎数，提高成穗数及成穗率，使籽粒产量中来自花后光合器官输送的比例增加，从而使产量提高，因而在旱地高产麦田应推广冬前深耘断根。6研究了降水量对旱地高产小麦耗水规律及产量的影响，拔节前降水多且占比重高，土壤供水量及占比重少，拔节后降水量减少且占比重低，土壤供水量及占比重高，利于在旱地高产麦田形成高产。

The results indicate that the effect of CA-FCM using rainfall and atmospheric perceivable water as covariants is better,for the physical covariant that is not influenced by catalyze is used as controlling factor and cluster analysis method is employed.The significant is more than 0.05.The effects of other methods are worse.

结果表明：协变量由降水量和整层大气降水量2个组成的CA-FCM方法，由于引入了不受催化影响的物理协变量作为控制因子，以及采用了聚类分析提高了对比区和影响区相关性，其评估效果最好，显著水平高于0.05；其他评估方法评估效果较差。

In addition to northern Fujian, northern Guangdong, and northern Guangxi and a few other regions, the annual average temperature is 19 ℃~ 22 ℃, the lowest month average temperature is 7 ℃~ 14 ℃, tea-year growth period 10 months or more, the annual precipitation is the most tea-growing areas in China, generally 12O0 mm ~ 2000 mm, of which Taiwan Province of abundant rainfall in particular, the annual rainfall often exceeds 20O0 mm.

是19℃22℃，最低月（1月）平均气温为7℃14℃，茶同比增长除了福建北部，广东北部，广西北部和其他一些地区，年平均气温期间10个月或以上，年降水量是最种茶中国地区，一般12O0毫米2000毫米，其中特别是台湾省雨量充沛，年降水量常超过20O0毫米。

The distribution of the underground rivers is consistent with the occurrence of the carbonate rocks in Chongqing.

同时利用地下河发育密度和多年平均径流模数，结合各地区多年平均降水量，对重庆市地下河水资源的分布规律进行了分析，得出地下河发育密集地区并不一定就是水资源量大的地区；降水量高的地区也不一定是地下河水资源量大的地区，二者在重庆市存在较大差异。

Based on the results simulated by PRECIS (Providing Regional Climates for Impacts Studies), which is developed in the Hadley Centre for Climate Prediction and Research, changes of surface air temperature and precipitation under SRES B2 scenario in South China during 2071~2100 are analyzed. It is shown that, compared to baseline (1961~1990), surface air temperature in 2071~2100 would increase by 2~4℃, precipitation in summer would increase in the north part to 22°N, while the precipitation in winter would decrease in the whole areas of South China. The climate trend of the surface air temperature would be positive, however the climate trend of the precipitation would be negative, the occurrence frequency of extremely high temperature events and extremely heavy precipitation events would increase.

利用英国Hadley气候预测和研究中心的区域气候模式系统PRECIS，模拟分析基于政府间气候变化专门委员会 2000年发布的《排放情景特别报告》中设计的B2情景下华南区域2071~2100年的温度和降水量的可能变化，结果显示：2071~2100年均地面温度相对于气候基准时段（1961~1990年）上升约2~4℃；华南区域未来夏季降水量在22°N以北区域较气候基准时段增加，而以南区域减少；冬季降水则表现为华南区域较气候基准时段减少。2071~2100年华南区域的温度气候趋势系数为正值，年均降水气候趋势系数为负值。2071~2100年的高温事件和强降水事件的发生频率均比气候基准时段明显增加。
