Taking the irrigation with reclaimed water of Dawukou Forest Park in Ningxia as an example, through the indoor test of one-dimensional dust columniation , the regular patten of pollutant shift in soil when irrigated with reclaimed water at different infiltration condition was studied.

摘要以宁夏回族自治区大武口市森林公园利用再生水灌溉为例，通过室内一维土柱试验模拟土壤的入渗过程，研究了不同灌溉入渗条件下污染物在土壤中的运移规律，结果表明：土壤的吸附作用是影响该地区土壤污染物迁移的主要因素。

Taking a winter wheat field (4 400 m2) of Jinghai county seed farm as experimental plot,sampling by regular grid with with 10 m ×10 m grids,48 sample points were oriented by GPS receipt machine to analyze soil water content at the depth of 0~20 and 20~40 cm in pri-winter,jointing stage and filling stage of winter wheat.The spatial distribution map of soil water of the winter wheat field using geostatistical analyst model of ARC/INFO was drew.And the spatial variability of soil water in vertical and horizontal direction was analyzed.The results could offer scientific evidence for the deciding of the exact time and quantity for winter irrigation.

以天津市静海县良种场内一块长约110m，宽约40m的冬小麦田作为试验区，采用规则格网采样，按照10 m ×10m设置格网，共设48个采样点，通过GPS手持机进行定位，分别于小麦越冬前、拔节期、灌浆期，利用便携式土壤湿度数据采集器对试验地各个采样点0~20、20~40 cm 2种深度土壤含水量进行了测定，利用ARC/INFO的地统计分析模块绘制了冬小麦3个不同生育期试验区土壤水分空间分布图，并分析了其垂直和水平方向的空间变异特征，以期为确定最佳灌溉时机和灌溉量提供科学依据。
