As far as time alignment is concerned, in a certain space, IR element distends in quantity and evolves in quality to accumulate IR as time goes by. While as far as space alignment is concerned, in some certain time, IR element has diversion and exchange in quantity and quality to make the IR element flow.

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。
