Suddenly ploughed tracts and irrigation channels appeared , and the glisten of flooded rice - fields ; and cranes preceded the suburbs of mari 刹那间，犁耕田和灌溉渠出现了，水稻田也在闪闪发亮；到达马雷市郊区之前还看到了一些起重机。
According to the definition in ramsar convention , wetlands include marshes , peatlands , wet meadows , lakes , rivers , floodplains , river deltas , tide flats , reservoirs , ponds , rice paddies as well as marine areas with water depths under six meters 按照《湿地公约》定义，沼泽、泥炭地、湿草甸、湖泊、河流、滞蓄洪区、河口三角洲、滩涂、水库、池塘、水稻田以及低潮时水深浅于6米的海域地带等均属于湿地范畴。
Based on the data of daily water withdrawal , rainfall and evaporation in 14 experimental paddy fields , which were varied in landform , soil type , drainage system , growth rule , and irrigation mode , with typical investigation , and analysis in the influence factors on water use , the research of water use regulation in paddy fields and its influence on water resources distribution was done . at the same time , the mathematical relation between the total water consumption and the growth days of paddy was founded 以2001年为基准年，通过对杭州市不同地形、不同土壤、不同渠系、不同种植制度、不同灌溉方式的典型水稻田灌水的逐日记录，结合降雨、蒸发监测值，实测了不同水稻田的灌溉水量及水资源使用量，并结合典型调查，分析了影响本地水稻用水的各因素的影响程度，研究了本地水稻的用水规律对本地水资源配置的影响。
The distribution and ecology of ge - xian - mi in rice fields of hefeng county in china were investigated . furthermore , the co2 concentrating mechanism ( ccm ) in cyanobacterium was reviewed and the utilization of inorganic carbon in ge - xian - mi in addition to its role in alleviating the photoinhibition were studied in the present paper 本文对葛仙米在中国鹤峰县水稻田的分布与生态学进行研究，综述了蓝藻的二氧化碳浓缩机制，并在此基础上对葛仙米无机碳利用及其在减轻光抑制方面的作用进行了探讨。
