The article adopted a new filtering-cloud composing technology used to monitoring drought,analyzed the property of Ts—NDVI characteristic space and the TVDI's indicating drought ability, put forward the TVDI compute model, grade standard, and the impact estimation method. The result indicated: 1 the decade-composed data obtained by the maximum surface temperature principle has better ability than the composed data obtained by the maximum NDVI on monitoring drought; 2 in the Ts-NDVI characteristic space,the dry side and the wet side almost are horizontal lines when the NDVI is on the small side, the temperature difference is about 45℃; 3 the TVDI has inequable level on monitoring drought as its value, the less TVDI indicates without drought occurrence, the bigger TVDI shows the drought certainly happened, the unsure drought conclusion mainly comes from the middle TVDI; 4 the monitored results of Sichuan hot-drought in 2006, obtained by the remote sensing and by the climate index, are basically consistent, the estimating error on the bearing drought crop area and on the drinking trouble population is within 10%.

采用了干旱监测合成滤云新技术，分析了Ts—NDVI特征空间属性和TVDI指数干旱监测能力，提出了四川伏旱TVDI计算模型、分级标准、和影响评估方法，结果表明：1按最大地表温度原则得到的旬合成数据比按最大植被指数原则得到的旬合成数据具有更强的旱情监测能力；2在Ts—NDVI特征空间中当NDVI较小时干湿边几乎同为水平直线，两者相差约45℃；3TVDI指数因其大小不同而对旱情的监测能力也不一样，较小时说明没有干旱发生，较大时则一定有干旱发生，中间段对干旱的监测具有不确定性；42006年四川伏旱遥感监测与气候监测结果基本一致，农作物受旱面积与饮水困难人口数估算误差在10%以内。

During the researchperiod, the researcher collects a great number of literatures and research data. On theadvanced bases, the paper summary the achievement of previous development innatural disaster risk research both in domestic and abroad for references. Starting fromearth systemic and scientific thought, the paper makes analysis on the maincharacteristics of natural disaster risk system and probes into the theories and methodsof natural disaster risk assessment. The paper apply Remote Sensing and GIStechniques to take apart the dynamic assessment ways and modes of natural disasterrisk in diverse scales cities, in order to provide scientific basis for urban disaster riskdecreasing and risk decision-making management.

For the tracking system, the means that can intellectively assist the fault diagnosis and maintenance is significant. Then we can avoid relying heavily on the experiences of the engineers and can reduce the probability of the event that engineers climb up to the antenna with heavy instruments when the faults turn out. For the data channel, to get the high-qualified remote sensing images, we need to get the quantitative data about how the factors influence the BER of Receiver .The data can help the design of receiver and the evaluation of the performance of a receiver. This thesis mainly contains those two parts.

对于跟踪系统，研究一套能辅助系统故障诊断及维护的智能手段是非常有意义的，这样系统维护时可以避免过多依赖技术人员的维护经验，特别是接收天线发生故障时携带仪器攀爬天线的情况；对于数据通道，面对高质量的遥感图像数据要求，我们需要得到影响接收机误码性能的各主要因素对应的量化数据，这些数据对于接收机的设计及性能评估是非常有帮助的。

Land cover of Shanxi Province had been monitored from 1980s to 2005.Based on remote sensing and GIS technique, analysis on spatial\|temporal characteristics of land cover change and driving factors was implemented.Results show that:(1)Changing area: Area of industrial and transportation land、rural settlement and a spot of grass land is increasing, on the other side, area of dry land, irrigable land, a spot forest land and bottom land etc is decreasing.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
