中文摘要：

为了研究采煤沉陷区积水对作物产量的影响,通过野外原位监测和室内实验分析,对采煤沉陷水域周围不同位置作物的生长状况、产量进行了研究。结果表明：采煤沉陷区积水改变了周围土壤的特性,并对不同位置的夏玉米植株株高生长和地上部干物质量的积累产生显著影响。在夏玉米拔节期、抽雄期、乳熟期和完熟期,沉陷水域对不同位置的夏玉米株高、地上部干物质量均有显著影响。采煤沉陷区积水对不同位置的夏玉米产量及其构成因素产生显著影响,随着距水域距离的增加,夏玉米产量及其构成因素受到的影响呈现减小趋势,且均显著低于对照。距沉陷水域4m范围内,夏玉米减产100%;6~10m范围内夏玉米产量分别降低了60.47%、40.41%、27.21%。该研究可以为耕地报损和采煤损害补偿提供理论参考。

英文摘要：

To study the effects of mining subsidence ponding on the crop yield, based on the field monitoring and laboratory analysis,this paper collects the crop samples from the different locations around the subsidence ponding. The results show that,the ponding changes the soil characteristics,and has significant impact on the plant height of maize at different locations and the dry matter weight of the aerial parts. During the elongation stage,tasseling stage,milk- ripe stage and full ripening stage,subsidence ponding has significant impact on the plant height of maize at different locations and the dry matter weight of the aerial parts. Mining subsidence ponding has significant impact on different locations＇ maize yields and its component,with the increase of the distance from the ponding,the impact on maize yields and its component is tended to decrease,all obviously lower than the control as well. Four meters away from subsidence ponding,the yields of maize reduces for 100%. Four meters to six meters away from the ponding,the maize yield is reduced by 60. 47%,40. 41% and 27. 21% respectively.
