The relationship between aboveground net annual primary production,aboveground average growth season production and long term climate change was analyzed in Stipa breviflora desert steppe in Inner Mongolia.

本文通过分析短花针茅草原植物群落地上净生产量、生长季节地上平均生产量与多年气候变化的相互关系，指出短花针茅草原近年气温有逐步升高的趋势，降水量的波动成随机性。

Results show that stratiform rain occupies more area and contributes more rainfall to the total than convective rain does at the 3 times.

结果表明：三个时次层状云降水在象素数量上及对总降水量的贡献上均比对流性降水大。

Precipitation of convection will diminish, while that of stratiform clouds will maintain, so the mixture clouds can bring stronger precipitation in a large area.

对流云的降水量不断减小，而层状云的降水不断维持，带来了大面积持续时间很长的降水。

The hydrologic cycle, a major topi c in this science, is the complete cycle of phenomena through which water passes, beginning as atmospheric water vapor, passing into liquid and solid form as precipitation, thence along and into the ground surface, and finally again returning to the form of atmospheric water vapor by means of evaporation and transpiration.

水文循环，作为该学科中的一个主要课题，指的是水所经过的诸现象的整个循环过程，开始时是作为大气中的水蒸气，转而作为雨、雪、露、雹一类的降水量经过液体和固体形态，由此而沿着地层表面分布或进入地层表面，最终通过蒸发和散发作用再度回复到大气水蒸气的形态。

Supported by GIS, maps were overlapped of normalized vegetation index, topograph, soils, government districts, yearly rainfall, yearly mean temperature, accumulated temperature during growing period of wheat, so as that ecological layers for wheat were stratified objectively and a base graph of non wheat image cell was plotted for average year.

在地理信息系统支持下，将处理好的归一化植被指数图与地形图、土壤质地图、政区图、年降水量图、年平均气温图、小麦生育期积温图等背景图件叠加，进行比较客观的小麦遥感生态分层，并制成常年非麦象元分布底图。

Form scale parameter we can see that probability of precipitation of rain day become bigger on the middle and lower reaches of Changjiang River, and discrepancy between upriver and the middle and lower reaches of Changjiang River also become bigger, the other areas change unapparent.

两时段中国夏季雨日降水量概率分布的形状参数在无条件和分条件下值都小于1，且地理分布形式都基本一致。

On the basis of long-term experiment, changes in soil organic C, N and dynamics of soil NO〓-N of cropping systems were investigated in gully area of the Loess Plateau by means of analysis of the 15-year soil samples, crop yield in following crop systems: 1 continuous winter wheat with unmanured , nitrogen, organic manure , phosphorus and organic manure , nitrogen and phosphorus , nitrogen, phosphorus and organic manure , 2 continuous alfalfa, 3 pea-winter wheat rotation, winter wheat-sainfoin rotation, and 4 bare fallow. A model was developed according to the organic C dynamics, and was tested by the long-term experiment.

本文以中国科学院长武试验站的长期试验（始于1985年）为依托，通过对典型处理8-15年的土壤养分、作物产量以及同期降水量等的系统分析，揭示了黄土旱塬区不同种植体系中土壤有机碳、氮的演变规律；阐明了长期施肥条件下土壤硝态氮的迁移积累机理；提出了目前水肥条件下黄土旱塬区冬小麦生产潜力及其提高途径。

To the east ,rains of 25 centimeters or more in areas stru ck the weste rn Gulf for Mexico .

在东部，25CM 或更多的降水量侵袭了西墨西哥湾。

This paper focus on the 3 LiaoYuan Regionalization ——mild-wettish zone in the northwest part, warm-cool half wettish zone in south central part and cold-cool half wettish zone in east part, according to agriculture natural climatic resources in LiaoYuan, and refer to the local unique physiognomy and topography , apply the heat and moisture factor target-oriented, relying on Precipitation in growth period of April-September as the Auxiliary index of General Ways invagination.

本文根据辽源地区的农业自然气候资源，参照本地独特的地势地貌，采用以热量和水分因子为主导指标，以4-9月生长期降水量为辅助指标的综合套叠方法，将辽源地区划分为西北部温暖湿润区、中南部温凉半湿润区、东部冷凉半湿润区三个农业生态气候区，旨在为当地党政机关合理开发利用气候资源，科学调整农业结构和布局，减轻和避免气候灾害，提供科学依据和参考。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
