The dissertion, after introducing physical geography situation and societal economic sitiuation of chongqing, has also analysed the basic feature of water resources in chongqing, at present the water resources utilization in chongqing is still in traditional phase. there are so many faults and shortcomings in water resources management system. the construction of water resources institutions and regulations is fallen behind. the supply of water resoures has not sufficiently satisfied the demand to water resources. the condition of water quality has not radically improved. soil losses is still serious. the incidence of flood and drought is very high. in accordance with present condition of water resources utilization in chongqing, the dissertion argues that it should strengthen people ' s understanding to water resources sustainable utilization for chongqing ; reform the present water rexources management system and have a try on water affairs management system in chongqing ; make effort to construction of water resources " institutions and regulations ; realize demand management, constuct save - water model society ; according to actual condition, strength water utilization constrution, then realize the balance between water resources supply and demand ; according to the idea of " control resources, conduct flow ", control water pollution, realize sanitary generation ; control soil losses and protect water enviroment ; construc t the system of flood control and diaster prevent

    在對重慶市的自然地理情況和社會經濟情況作了介紹之後，還分析了重慶市水資源的基本特徵，目前重慶市的水資源利用還處在傳統的開發利用階段，水資源管理體制還存在許多弊端，水的法規制度建設也相對落後，水的供給還不能完全滿足需求，水質狀況沒有得到根本性的改善，水土流失還很嚴重，水旱災害發生的頻率比較高。針對重慶市水資源利用的現狀，本文提出：應加強對水資源持續利用的認識；改革目前重慶市的水管理體制，嘗試水務局管理體制，相應加強水的法規和制度建設，實現需水管理，建立節水型社會；根據實際情況，加強水利建設，實現水的供需平衡；依據「控源導流」的思想控制水污染，實現清潔生產；治理水土流失，保護水環境；建設防洪減災體系。
  2. Firstly, the status of our nation ' s water resources, flood and arid hazards is overviewed to illustrate the necessity for study on dynamic control of flood season limited water level. disadvantages in traditional limitsd water level design, static control of limited water level design, static control of limited water level and fuzzy limited water level curve are pointed out, and mending methods for these are introduced. dynamic control and its key problems are analyzed hi next section. the allowable range of limited water level is determined, so as the allowable extreme risk index. the definition of extreme risk is re - illustrated, risk analysis methods in reservoir operation is discussed either. according to the definition of extreme risk rate, the allowable extreme risk rate of reservoir is systematically demonstrated with variant extreme risk indexes and flood season limited water level

  5. The data used in the risk assessment of regional natural disasters imply the information not only on time but also on space. when the spatial information of the data is incomplete, it is necessary to optimize the data in order to reduce the error of the assessment. in the counterpart of the paper in last issue of the journal the theoretical investigation of the problem was carried out and the imcomplete information occured in risk assessment of regionalnatural disasters were class ifiedinto two types with treatment of interpolation model and correcting model res pectively. the former model is for insufficiency of the data and the later is for the case in which the accuracy of the data is not enough. inthispaper, taking the flood sustained by rural area plant in hunan province as an example, it is explained how to use the models to calculate. the models are examined as well

    區域自然災害風險評估中所用的數據不僅具有時間的意義，而且具有空間的意義，當數據的空間信息不完備時，需要對其進行優化處理，以減小風險評估的誤差，作者在本刊上一期的一篇文章中已進行了這方面的理論探討，將區域自然災害風險評估中所遇到的空間不完備信息分為兩類，分別用插補模型和校正模型進行了處理，插補模型是針對空間數據缺失情況的，而校正模型是針對空間數據不符合精度需要情況的，本文以湖南省農村種植業水災為例，進一步說明如何應用這些模型來進行計算，並對其進行了檢驗
