First,this article introduce the research meaning of the pit's environment effect by pit's dewatering.

首先讲述了基坑降水对周围环境影响的研究意义。

In order to put to use in the operations, 87(≥0. 1mm) samples of fating to forecast in 3 years can be summarized into 3 kinds 10 types according to weather situation.

为在气象业务预报中投入使用，本文对两图三年中共87个（≥0.1mm）漏报个例，依天气形势分为3类10型，分别研制短期降水订正预报指标。

Antarctic sea-ice oscillation index with a seesaw pattern is defined Using NCEP/NCAR reanalysis girds data of monthly Antarctica sea-ice concentration from 1973 to 2002. The Relationships between the index of winter and the summer precipitations in China as well as the onset date of the summer East Asia monsoon are presented.

利用NCEP 1973-2002年逐月南极海冰密集度格点资料，定义了具有跷跷板式变化规律的南极海冰涛动指数，分析了冬季南极海冰涛动指数与我国夏季降水及东亚季风爆发时间的关系。

Less rainfall in spring is not advantage to egg's breaking ground and hulling and to nymph's feed getting. The egg grows rapidly and has high imago ratio under condition of apprpriate temperature and 3~10mm rainfall per ten days.

春季降雨过少，既不利于蝗虫的破土出壳，又不利于出土蝗辅取食，而在适宜温度范围内每旬有3~10mm的降水，则蝗卵发育最快，出土成虫率最高。

Pure-remote sensing information models are free of the numerous distributional parameters that are difficult to obtain in vast area. The following sections are included in the study.(1) The VCI and SVI based on time-series NDVI data are used to analyse regional drought and the following results were reached: As the vegetation growth status index, the response of VCI and SVI to precipitation was land cover type, temporal and site specified. So VCI and SVI have little information about drought when used to monitor regional drought especially in China that has a mountainous topographty.(2) Based on the interpretation of NDVI-Ts space, NDVI and land surface temperature was combined to construct NVDI-Ts space from which the TVDI (Temperature Vegetation Dryness Index) was obtained with line ratio method and normalized slopes method. When compared with the topsoil moisture measured in situ, TVDI are competent in regional drought monitoring. Illumed by the NDVI-Ts space, we combined the NDVI with day/night land surface temperature difference and apparent thermal inertia to construct NDVI-ΔT and NDVI-ATI spaces from which the DVDI and AVDI were estimated respectively with 8-day composite MODIS 〓 product and 16-day composite MODIS NDVI product.

具体包括以下几方面的内容：(1)VCI和SVI在干旱监测中的作用评价：探讨利用NDVI时间系列数据建立的植被状态指数和标准植被指数评价区域干旱的可行性，研究结果表明：VCI和SVI作为植被相对生长状况指标，对降水的响应随着植被覆盖类型、时间和空间等而表现出不同的敏感性，因此在大区域干旱监测中，特别是我国这样地形复杂多样的国家，VCI和SVI在干旱监测中的作用都是有限的；(2)利用TVDI评价全国干旱等级分布：结合陆地表面温度和植被指数建立NDVI-T〓空间，在NDVI-T〓空间物理意义理解的基础上，分别采用线段比值法和斜率归一化法构建温度植被干旱指数，并利用TVDI研究了我国2000年3～5月份各旬的干旱分布，取得比较满意的结果。

According to engineering exploration and lab tests data and field investigation, the deformation mechanism of the landslide has been discussed. The landslide stability has also been calculated and analyzed under the conditions of impounding and precipitation by means of limited equilibrium theory.

根据野外现场调研和室内试验、工程勘察资料，探讨了天池口滑坡的变形机制，并运用极限平衡理论分析了滑坡在蓄水和降水时的稳定性。
