1) Datong Lake-polder
大通湖垸
1.
In the paper,on the basis of the two-dimensional flow model and by applying the finite volume method and unstructured mesh,the waterlogging and drainage of the Datong Lake-polder with different precipitations and floods were studied.
以洞庭湖腹地大通湖垸为例,基于平面二维水流数学模型,采用有限体积法和非结构网格,研究该区域在不同外洪条件与不同降雨组合条件下的沥涝情况,得出了区域内涝灾分布情况及致涝率,并定量计算分析了外洪水位变化对内涝造成的不利影响。
2) recovering the flood storage
退垸还湖
3) protective embankments in lakeside
湖垸农业
1.
Huyuan(protective embankments in lakeside areas)is the basic unit for wetland agriculture of Dongting lake region.
分析了洞庭湖的兴衰、演变与湖垸农业的关系;认为洞庭湖区的洪涝灾害是长期泥沙淤积与大规模围垦的必然结果:泥沙进入洞庭湖淤积,是形成湖垸农业的基础;围湖垦殖是泥沙淤积的结果,大规模围垦加速了洞庭湖的萎缩;湖盆的急剧萎缩,减少了湖泊的调蓄能力,是洪涝灾害发生的直接原因;湖垸农业就是一部先淤后垦、先垦后围、围湖垦殖、湖垸转换的历史;在分析洪涝灾害规律的基础上,总结提出了退田还湖区几种替代农业发展模式。
4) building dikes from lakes
围湖筑垸
1.
,it is mainly resulted from destroy of vegetation,loss of water and erosion of soil,from which Hudu,Ouchi and Songzi three tributaries of Jinjiang River lashed and some man-made factors such as building dikes from lakes in scale in Ming-Qi.
究其原因 ,除汉寿地处洞庭湖盆最低洼地带 ,沅水水流量、降雨量极为充沛等自然因素外 ,主要是因为植被的破坏、水土的流失和荆江的虎渡、藕池、松滋三口此时期冲成以及明清大规模的围湖筑垸等人为因素造

钱粮湖垸
6) polders in Dongtinghu Lake area
洞庭湖堤垸
