It has not only the effect of deducting flood peak and retenting flood but also a little decrease of the volume of floods into the yellow river 不同时期堤防的建设标准及河道条件不同，夹滩地区的滞洪作用也不同。
2.
The main buildings of resisting flood such as cofferdam and diversion tunnel without the capacity of flood control play a role in flood detention 围堰和导流洞作为渡汛的主要设施，其没有调节洪水的能力，只能对洪水起到一定的滞洪作用。
3.
Flood storage effect in the beach between yi river and luo river is different from natural condition because of the dykes of the two rivers 伊洛河河道两岸堤防的存在使夹滩地区的滞洪作用不同于天然滞洪区，它不仅对入黄洪水起滞洪削峰作用，而且对洪水总量还略有削减。
4.
The efficiency of flood storage by the beach area are various according to the dyke construction standard and river condition in different periods 经对1935 、 1937 、 1954 、 1958 、 1982年实测洪水资料的分析知，夹滩地区对入黄洪水的滞洪作用与洪水量级大小、洪水过程胖瘦、堤防决溢程度等因素有关。
5.
Based on the analysis of flood data of 1935 , 1937 , 1954 , 1958 and 1982 , the flood storage effect is related to flood volume , flood process , intensity of dyke break and others 在现状堤防条件下，如果再发生1954 、 1958年量级的洪水，在确保洛河北大堤安全的情况下，有计划地使用夹滩及南岸滞洪区滞洪，则夹滩地区对入黄洪水的削峰率可达20 % 25 % 。
6.
Large - scale changes of landscape structure cause the degradation of functions of storage and drainage in watershed wetland , which are reflected by loss of flood holding capacity , increase of surface runoff and decrease of confluence time etc 景观结构的巨大改变引起了流域湿地贮、排水功能的衰退，主要表现为滞洪、消能空间的丧失，径流量的增加和汇水时间缩短等。

In the future , we will look after both sides on river - flood control and nature landscape and put more effort on design ecological pond , flood retention pond , wetlands and riverside - park , to restore and create diversity and beauty to water environments , and to enhance the overall quality of life of our citizens 展望未来，本局赓续秉持以生态防洪安全为内函主轴，配合水岸景观为外在目标之理念，依各河川特性，规划生态池、滞洪池、水域湿地及亲水公园等，营造多元化生态环境，达到人水永续之目标。

Forests as an adjuster for ecological balance in mountain areas play important roles in soil and water conservation , runoff and silt retardance etc . especially , forests are regarded as " forest reservoir " due to their great hydrological regulation functions through canopy , undergrowth , litterfall and soil layers 森林是山地生态平衡的重要调节器，特别是其水源涵养、理水保土、缓洪滞淤的功能对于山地面积大的福建省显得极为重要。森林通过林冠层、林下植被层、枯枝落叶层以及土壤层发挥良好的涵养水源、保持水土、削峰滞洪等“森林水库”的功能。

The sixth , build the floodwater utilization model , put forward the concrete measure and way to solve chagan lake water resources , and analyzed the effect on the flood detention of jilin chagan lake wetland the seventh , analyzed the influence of floodwater utilization to the environment , and put forward water resources protection measure of jilin chagan lake wetland 6 、建立了吉林省查干湖湿地洪水利用模型，提出解决查干湖湿地水资源的具体措施和途径，分析查干湖湿地蓄滞洪作用。 7 、分析评价了吉林省查干湖湿地洪水利用对环境的影响，提出查干湖湿地水资源保护措施。
