Using the observed data of spring-sowed two years fresh alfalfa growth condition and parallel climatic conditions,analysis is made of the alfalfa's growth height and the speed variation rule with time in the loess plateau area of East Gansu,and the correlation dependence of dry matter and the fresh grass with the activity accumulated temperature.

利用春播两年生紫花苜蓿生长状况和平行气候条件观测资料，分析陇东黄土高原地区紫花苜蓿的生长高度和速率的时间变化规律，干物重和鲜草重与活动积温的相关关系；根据牧草气候生产力的光合产量和温度及降水订正模型，计算紫花苜蓿的气候生产潜力。

The result showed that the yields of spring wheat and naked oats were negatively related to the monthly average temperature and the sum of them; the yield was positively related to the monthly precipitation and their sum.; and the yield didn't have distinct relation to the monthly sunshine hours.

结果表明，武川小麦和莜麦的丰歉与生长季各月的平均气温及其总和呈负相关，与生长季各月降水量及生长季降水之和呈正相关，与日照时数关系不显著。

In permafrost region, most of the rainfall is always freezing in the ground or used to supplement the deficit of soil moisture and don't product runoff directly, there's only a better correlation on runoff at spring and summer flood.

多年冻土区降水大部分冻结在土壤中或者用来补充土壤水分的亏缺，不能直接产流，只有在春汛和夏汛期间与径流保持较好的相关关系。

Furthermore, the impact factor on runoff showed that, each stage has different impact factors, soil temperature and soil moisture above 65 cm plays a leading role in spring flood; in summer dry season, relation of soil temperature and moisture above 40 cm and runoff is negative correlation, the deeper soil temperature and soil moisture plays a leading role; temperature and precipitation plays a leading role in summer flood; in autumn dry season, the impact factors are soil temperature, soil moisture and temperature.

径流影响因子分析的结果表明：径流过程中不同时段具有不同的主导因子，春汛期主要是65cm以上的土壤温度和水分起主导作用；夏季枯水期40cm以上土壤水分与径流是负相关，深层地温和土壤水分起主导作用；夏汛期气温、降水起主导作用；秋季枯水期的影响因子依次为土壤温度、水分及气温。

Moreover, with the assistance of grey series forecasting model and the rule of the annual precipitation, the annual average precipitation, groundwater flow field, groundwater level and spring flow in the future under current exploitation circumstances were forecasted. If 2010 is a high flow year (guarantee ratio 20%), or median flow year (guarantee ratio 50%), or even low flow year (guarantee ratio 75%), the underground water level of Heilongdong spring in flood season will exceed 130 m, or reach 130 m, or even below 130 m, and the spring flow in flood season will exceed 10 m^3/s, 7 m^3/s, 5 m^3/s respectively.

以灰色序列预测模型为辅助手段，结合历年的降水规律，对未来现状开采条件下的年均降水量、地下水流场、水位及泉流量进行了不同保证率条件下的预测，若2010年为丰水年（保证率20%）、平水年（保证率50%）、枯水年（保证率75%，黑龙洞泉汛期地下水位标高分别为超过130m、达到130m、低于130m，汛期泉流量分别为超过10立方公尺/s、7立方公尺/s、5立方公尺/s。

This paper conducts the computation classification for the spring flood and drought situation in He Zhou by using the spring precipitation data in four weather stations of He Zhou during 1965-2004,and the z index,and the index of regional flood and drought .

利用贺州市四站1965~2004年春季降水资料，运用z指数和区域旱涝指数对贺州地区春季旱涝情况进行计算分类，并对重旱涝典型年份500hPa环流特征量和4月平均环流场展开分析，发现：贺州地区春季极易发生局部旱涝灾情，90年代以来重旱涝年份出现频率明显增大；在重旱年副高强度强，西伸脊点明显偏西，南支槽偏西偏弱，极涡中心偏东，亚洲中高纬高度偏低，在重涝年则相反。

But that's not all -- green roofs are a great way to handle water management in urban areas with overwhelmed sewerage systems (green roofs soak up excess precipitation), provide sanctuaries for urban wildlife, and actually extend the life span of the roof itself.

但还远不止这些优点——绿色屋顶以其强大的排水系统，能有效管理城市排水问题（绿色屋顶吸收大量突然降水）。绿色屋顶为城市种的野生动物提供避难所，同时也延长了屋顶绿化本身的寿命。

Vertical well construction is used by artificial excavator and self-sinking technology.

采用辐射井降水方法，在滂江街站穿越沈海立交桥段布设4眼辐射井。

There are two basic and conventional contamination accumulation modes,one is the common slow contamination accumulation and the other is a sea fog type of rapid contamination accumulation with high conductivity that naturally takes place in coastal areas.

在常规的缓慢积污和沿海的、自然的、高导电性的海雾型快速积污2种基本积污形式之外，内陆地区出现与人类活动相关的、高导电性的降水降雪型快速积污。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
