In the end it suggests some counter-measures, including: developing cage acquiculture in the bends and branches as the stradegy direction in cultivation program; developing high-density flowing aquiculture making use of the stream resources; selectively developing dam-intercepting bends acquiculture and quality pool fishery; intensifying the protection and utilization of the natural fish resources so as to develop special variety and establish fry production base; developing large-water-area throw-in and enrichment and culture fishery and halieutics; protecting ecological environment and establishing economic fish and rare fish protection district; perfecting fishery institution and intensifying fishery management and bettering the fish breeding; developing tourist and fishing industry; establishing related mechanism including government control mechanism, market guiding mechanism, management and running company system, sales market share system, farmer organizing and uniting system, leading enterprise leading system; increasing the investment to the fishery industry in the area

文章最后提出发展三峡水库渔业的对策包括：养殖项目的战略定向为利用库湾库汊，发展网箱养鱼；利用山溪流水资源，开展高密度流水养鱼；利用高水位区库湾，有选择地开展坝拦库湾养鱼和精养池塘渔业；强化天然鱼类资源保护与合理利用，进行特色品种的开发和苗种生产基地的建设；大水域放流增殖，发展捕捞业；保护生态环境，建立经济鱼类和珍稀鱼类保护区；健全渔政机构、加强渔政管理、做好鱼类繁殖；积极发展游钓业；建立与渔业发展相适应的配套机制包括政府调控机制、市场导向机制、管理运营公司制、营销市场股份制、农民组织协会制、龙头企业带动制；增加三峡水库渔业的资金投入。

Based on the eco- environment function, confirmed the constitution of eco- environment water demand(including the inside of the watercourse.and the ecological water demand of the outside of the watercourse such as ecological water demand of economical crop, of lake or reservoir and of cities.).③Analyzing the physical geography, hydrography, economy characteristic and water resource status, getting the proper calculation method. The Tennant applied to the eco- environment water demand of inside of the watercourse, woodland minmum eco- environment water demand calculation method applied to the eco- environment water demand of woodland, water ration method applied to farmland the eco- environment water demand, water evaporation method applied to the reservoir eco- environment water demand.

本文以流域生态环境需水为主要研究对象，因此重点阐述了流域生态环境需水量的分类和计算方法；②通过分析流域生态系统构成与流域生态环境功能，并分时段和河段考虑，确定了桃花江流域生态环境需水量的组成，即包括维持现状河道生态环境功能现状的现状生态环境需水量与流域生态环境改善的生态环境需水量，前者包括河道内生态环境需水量(维持河道基本生态功能需水量、维持河道自净稀释功能需水量、补充地下水水量及美化流域景观娱乐需水)与河道外生态环境需水量(流域内植被、森林、农田的需水量和与河道相连的池塘、水库等的需水量)；后者还包括为治理改善流域生态环境而拟规划林业生态建设所需水量；③对桃花江流域的自然地理、水文地质和社会经济特征以及水资源现状及其主要生态环境问题进行了综合分析，提出了适合桃花江流域的生态环境需水量计算方法，即采用Tennant法计算河道内生态环境需水量，采用林地最小生态环境需水量法计算林地生态环境需水量，采用需水定额法计算农田生态环境需水量，采用水面蒸发法计算水库、池塘生态环境需水量。

A discrete Logistic model was applied to icefish populations analyzing and simulating the variation of the annual catchment production of icefish populations for four typical lakes/reservoirs such as Dianchi lake in China, it was found as evidence of chaos in a natural eco-system that the parameters of icefish populations for four lakes/reservoirs fall into chaotic region under normal circumstance.

将离散Logistic模型应用于银鱼种群数量变动研究，通过对滇池等4个典型湖泊或水库的银鱼年产量变动的初步分析和模拟，发现所有的湖泊或水库银鱼产量的参数值都落入了混沌区间，在自然生态系统中找到了混沌行为的证据。

The results of water quality monitoring conducted in the period of one year after three-gorge reservoir impoundment up to EL.

三峡水库135 m蓄水后1年来的水质监测结果表明：三峡水库135 m蓄水对库区干流江段未造成明显影响，但对库区部分支流局部区域的水质造成了较为明显的影响。

The reservoir-induced seismicity is formed due to impoundment, which changes the frequency and intensity of earthquakes at the reservoir area.

水库诱发地震指在水库蓄水后，由于库水作用，改变了库区原有地震活动的频度和强度，而形成的地震。

In order to study the triggering mechanisms, we try to calculate the seepage field by finite element method and explore the relationship between the seepage with initial impoundment and the seismicity in the reservoir region.

为探讨库水在地震形成机制中的作用，本文试图通过新丰江水库渗流场的有限元计算，对新丰江水库蓄水初期库水渗流与地震的关系进行初步研究。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
