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。

The results showed as:(1)Gegen decreases fasting insulin and insulin resistance index and increases insulin sensitive index of rats of insulin resistance induced by dexamethasone significantly;(2)Gegen can improve glucose tolerance of rats of insulin resistance but not to alloxan indued diabetes mice;(3)Gegen increases glucose intake of 3T3-L1 adipocytes and improves the insulin resistance of 3T3-L1 adipocytes induced by dexamethasone significantly;(4)Gegen can activate peroxisome proliferator- activated receptor gamma, make it bind to PPAR response elements;(5)Gegen can up-regulate mRNA expression of PPAR v ,aP2 and adiponectin.

结果表明：①葛根显著降低地塞米松诱导的胰岛素抵抗大鼠血清胰岛素水平和胰岛素抵抗指数，升高胰岛素敏感指数，改善大鼠的胰岛素抵抗；②葛根显著改善胰岛素抵抗大鼠的糖耐量，但对四氧嘧啶糖尿病小鼠的糖耐量没有明显的作用；③葛根显著增加胰岛素抵抗3T3-L1脂肪细胞对葡萄糖的摄取，改善地塞米松诱导的3T3-L1脂肪细胞的胰岛素抵抗；④葛根能促进HepG2肝癌细胞过氧化物酶体增殖物激活受体γ与靶基因的特异DNA序列结合，对PPARγ及其下游基因的转录具有激活作用；⑤葛根能够促进PPARγ及其下游基因脂肪酸结合蛋白(aP2)、脂联素mRNA的表达。

By using the normalized difference vegetation index extracted from CBERS-02 data and the leaf area index data obtained from field measurement, this paper analyzed the relationships between the NDVI and the LAI of total samples of meadow, marsh vegetation, shrubs, and islanded forests of the wetland vegetation in Honghe Nature Reserve of Sanjiang Plain. The linear and non-linear regression models between NDVI and LAI of different wetland vegetation types were established, and the spatial distribution of LAI in the Honghe Nature Reserve was mapped.

The interlayer oxidized zone and the concentration of uranium has the typical characters of low temperature geochemical processes. Interlayer oxidized zone can be defined from the bedrock to horizon C under hypergene weathering by such parameters as chemical metamorphosing、index of chemical weathering and index of mineral chemical differentiation.(2)Major elements can be divided into sensitive group、 active、 weak active and inert groups according to chemical metamorphosing parameter and fractional migration potential. For major elements of multivalent in the active group( Fe_2O_3、 FeO) and U, the migration and concentration trend in interlayer oxidized zone is apparent.
