Abstract : the qiantang estuary with violent hydrodynamic conditions is well known for its tidal bore . the regulation of the estuary in the past , especially the progress since the founding of new china are reviewed . the principles of the regulation and planning of the qiantang estuary formulated in 1960s are expounded , i . e . , to narrow the river to reduce the tidal prism , and to increase the ratio of the river flow to tidal discharge . the experience of estuary regulation / reclamation is summarized , especially the engineering measures to protect the groin head and to use polder dykes as sea defense works . finally , the effect is analyzed of the large - scale constraction / reclamation in the estuary on the tides , flooding high water level , estuary bed and the northern deep waterway in the hangzhou bay 文摘:以涌潮闻名的钱塘江河口，动力强劲，破坏力极大.回顾钱塘江河口历代治理情况，重点记述1949年以来治理工作的进展，论述60年代提出的钱塘江河口治理规划的指导思想，即缩窄江道，减少进潮量，增大山潮水比值的整治原则.总结整治规划实施过程中治江围涂经验，特别是“以围代坝”和丁坝坝头保护等工程措施.分析钱塘江河口大规模治江围涂后对钱塘江河口潮汐、洪水位、河床以及杭州湾北岸深槽的影响

Enforce the supervision and monitoring on the retuned lake from polder , and establish ecological immigration area and nature reserves , by adapting strict management regulations and enforcing lawful management , guarantee the project of establishing immigration area reach the proposed target , and the ecosystem is improved and restored 对洞庭湖区的单退和双退堤垸，分别建立生态移民区和严格自然保护区，通过制定严格的管理法规和强化执法管理，确保移民建镇工程收到实效，生态得到有效恢复。

In the paper , river and the downstream area of dike are regarded as a whole system , and hydraulic model of coupling 1 - d river and gradual dike - break is established , therein the preissmann implicit difference scheme is applied to main river , and the fvm ( finite volume method ) is applied to the breach and polder 本文将河道与堤坝下游区域视为一个整体，对于单一河道采用preissmann四点隐式差分格式计算，对于溃口及圩区采用有限体积法，建立了一维河道与堤坝渐溃耦联的水力模型，也是一维、二维耦合的水流模型。

The main contents include : water environment , marine sediment and the trend monitoring of marine life quality ; at the same time , to consolidate the monitoring of the functional zones , such as seashore bathing places , oceanic reserves , marine aquafarms ; to set up the seashell monitoring and controlling zones in the sea areas of both pingtan and yunxiao at the first time ; to carry out the statistical monitoring of polder , exploiting sea sand , spartin aallerni flora , terrestrial sewages , etc . , to carry out monitoring of the total quantity of pollutants into the offshore marine areas in the min river , the jiulong river as well as the municipal sewages of xinlin industry in xiamen and jiaocheng in ningde ; to carry out the red tide monitoring in the offshore marine areas of fujian province ; to implement time - lapse , pointing and continuous red tide monitoring of high frequency and high intensity in the sandu gulf , the min river estuary and offshore marine areas of xiamen 主要内容包括水环境、海洋沉积物和海洋生物质量的全海域环境趋势性监测，同时加强了海水浴场、海洋保护区、海水增养殖区等功能区监测；首次在平潭和云霄海域设置了贝类监控区；开展了围填海、海砂开采、互花米草、陆源排污口统计监测；并在闽江、九龙江、厦门杏林工业排污口、宁德蕉城市政排污口邻近海域开展污染物入海总量监测；在全省近岸海域开展赤潮监视监测，对三都湾、闽江口、厦门近岸海域赤潮监控区实施高频率、高密度的定时定点连续监测。

Then , with the help of gis , i selected 8 soil fertility factors mentioned above and soil texture as parameters , used blocks generated by overlaying each factor theme as assessing unit , modified nemoro fomular , and then i assessed the overall soil fertility quality of wujin city , we know : the soil fertility quality of the city is generally medium or worse , in it , the district of riverine polder the district of menghe even fields the district of taige even fields and the district of hilly lands are on " worse " level , and the district of zhengheng polder the district of lakeside polder and the district of taoge even fields are on " medium " or " better " level 接着在gis支持下，选取以上8项土壤肥力要素并加上土壤质地作为参数，以各要素图层叠加产生的图斑作为评价单元，修改内梅罗公式，对武进市土壤肥力质量进行综合评价，得出：土壤肥力质量中等偏下，其中，沿江圩田区、孟河平田区、太涌平田区和低山丘陵区主要处于“较差”水平，而郑横圩田区、沿湖圩田区、洮?平田区主要处于“中等”及“良”水平。
