It is expected that the grain size of bottom sediment at the landward limit of the Yangtze Estuary will increase further in the coming decades due to a more dramatic reduction of suspended sediment after the Three Gorges Project and other upstream largescale reservoirs.

随着三峡水库的正常运行和其它大型水库的建设，预计未来几十年长江上游悬沙来量将进一步大幅度下降，可以预计，长江潮区界河段的床沙粒径将继续呈现增大的趋势。

It is expected that the grain size of bottom sediment at the landward limit of the Yangtze Estuary will increase further in the coming decades due to a more dramatic reduction of suspended sediment after the Three Gor-ges Project and other upstream large-scale reservoirs.

随着三峡水库的正常运行和其它大型水库的建设，预计未来几十年长江上游悬沙来量将进一步大幅度下降，可以预计，长江潮区界河段的床沙粒径将继续呈现增大的趋势。

On tne basis of reviewing the metnod of calculating firm energy of draw-down period and considering the conflicts between the hydropower and irrigation water requirement, this paper proposes a modificative method, applying multipurpose decision of system engineering combined with incremental dynamic programing with analysis to obtain an optimum program which would yield the maximum economic benefit.

本文针对水库设计供水期保证电量计算方法存在的问题，和发电与灌溉用水等矛盾，应用系统工程多目标决策，和增量动态规划与分析相结合的方法，提出了能使电力系统基建投资省、保证电量大、和灌溉用水多的综合利用效益高的优化方案；同时还得出了具有长期予报的水库供水期最优调度的一般规律，应用该规律能迅速方便地得出最优方案。

First of all, the paper discussed the significance of sustainable development, made an analysis on background (circulation, management, environment and social economy development condition of the surrounding ecosystem). Then, the author carried on inquisition, data analysis and summary and made calculation and demonstration on the safe stability of the dam, and discussed the risking obviation and reinforcing technique, which gave premises to sustainable development.

论文首先论述水库可持续发展战略的必要性和意义，然后对沙河水库基本情况(运行、管理、周围生态环境，库区经济发展状况等)进行实地调查研究，将调查资料归纳、分析、总结，在此基础上对大坝的安全稳定进行计算和论证，讨论了大坝主要的除险加固技术，以此作为可持续发展研究的前提。

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。
