Through simulation and computation, some critical values to contral interferences are obtained. These values have directive significance to the design and deployment of WRAN.(4) New methods to measure and analyze spectrum aredevelopedAccording to the shortages of previous spectrum measurements, new methods to measure spectrum occupancy in wide-band and multi-point synchronously is proposed in this dissertation, and the tests last a whole week; the relativities of licensed services are considered when test points are selected. More importantly, data mining and in-depth analysis are carried out with the huge amounts of test data, and a channel analysis method using Channel Vacancy Duration and Service Congestion Rate are proposed. The spectrum relativities of 3-dimension in time, space and frequency are researched also. The correlativity between channel state and history information is discoved, and which will provide the scientific basis to channel modeling, spectrum analysis and decision of CR users.

4提出了频谱测量与分析的新方法针对以前频谱测量工作存在的不足，本文提出了多点同时广域频谱测量方法，测量工作持续了一周的时间，同时考虑了测量地点的选取和频谱授权业务之间的相关性；对测量得到的海量数据进行了数据挖掘和深度分析，提出了使用信道空闲时间(Channel VacancyDuration，CVD)和业务拥塞率(Service Congestion Rate，SCR)进行信道分析的方法，研究了频谱之间的时间、空间、和频率三维立体的相关性，发现了信道状态和历史信息的关联性，为CR用户的信道建模、频谱分析和决策提供了科学的理论依据。

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。
