The synchronous observations of deformation and gravity before and after impounding are analyzed comprehensively , and the possible effect on the seismogenic environment and potential seismic source is discussed and a new idea about reservoir earthquake is presented by developing a numerical model to analyse the change of tectonic stress field 综合分析了三峡水库蓄水前后形变、重力等同步观测资料；论述了蓄水库首区孕震环境与潜在震源可能的影响，并提出了一些研究设想。
In order to achieve this goal , this research will has the following four specific objectives : understanding the level of fish consumption in china and possible factors that affect the fish consumption ; developing a systematical modeling frameworks and complete demand system for food and fish demand study ; exploring the consumption behavior of both urban and rural consumers in china by estimating model of fish demand system and model of food demand system respectively , analyzing influence of various factors on the demand for fish and other foods quantitatively ; discussing the future change of aggregate amount and the structure of fish demand based on the result of the research , so as to provide basis for decision making in fishery production structure changes and rational utilization of fishery resources 本项研究的总目标是探讨影响水产品消费的各种因素，为预测未来水产品需求和生产结构调整提供依据。为达到这目标，本项研究分为以下四个内容：了解我国水产品消费水平和结构及其可能的影响因素；建立水产品需求系统模型；通过分别估计食物和水产品需求系统模型，探讨我国城乡居民消费行为，定量分析各种影响因素对水产品及其他食品需求的影响；根据研究结果，讨论未来水产品需求总量和结构的变化，为优化渔业生产和合理使用渔业资源提供政策依据。
