Result showed that, with the controlled facility, the water storage is about 19×10^3 m^3/km of in the main drainage canal, the groundwater table in farmland is raise about 0.3 to 0.5 m and the crop water use is increased about 50 to 80 mm comparing with the non controlled main drainage canal.
结果表明,单位长度大沟年调蓄水量为1.9×10^4立方公尺/km左右,其影响范围内的农田地下水位较无控制大沟平均抬高约0.3~0.5 m,每年可增加作物对地下水的直接利用量50~80 mm,区域年农田水资源调控总量110 mm左右,约占当地年均降雨量的13%;只要控制合理、管理得当,不会因此而影响排水系统对农田涝渍的有效控制或降低原有排水工程的除涝降渍标准。

Our results showed 1 The changes in trends of leaf traits response to the rainfall gradient differed either with species or with a specific trait; 2)The same trends were found at the functional group level, However, leaf traits for grasses tends to be less sensitive, then for forbs, and the legumes is the most sensitive functional group along the rainfall gradient, indicated that the Grass function group is quite strong to the soil moisture content tolerance, and which certainly explained to the local vegetation distribution and the substitution between species.
主要结论如下:1 叶片性状在降雨量梯度上的变化趋势在物种水平上表现出多样化的特点,性状的变化趋势是否有显著的格局取决于物种或特定性状。2 叶片性状对水分梯度的响应在功能群水平上表现出各自的特点,Grass功能群对水分梯度的响应敏感性较低,Forb居中,Legume表现出较强的敏感性,表明Grass功能群对水分的耐受性比较强,这在一定程度上解释了当地克氏针茅草原上目前以禾草类为主的现状,对物种之间的替代有一定的指示性。
