| 1 | Effects of emitter discharge rates on soil salinity distribution and cotton(Gossypium hirsutum L.) yield under drip irrigation with plastic mulch in an arid region of Northwest China显示文摘A field experiment was carried out to investigate the effects of different emitter discharge rates under drip irrigation on soil salinity distribution and cotton yield in an extreme arid region of Tarim River catchment in Northwest China.Four treatments of emitter discharge rates,i.e.1.8,2.2,2.6 and 3.2 L/h,were designed under drip irrigation with plastic mulch in this paper.The salt distribution in the range of 70-cm horizontal distance and 100-cm vertical distance from the emitter was measured and analyzed during the cotton growing season.The soil salinity is expressed in terms of electrical conductivity(dS/m) of the saturated soil extract(EC e),which was measured using Time Domain Reflector(TDR) 20 times a year,including 5 irrigation events and 4 measured times before/after an irrigation event.All the treatments were repeated 3 times.The groundwater depth was observed by SEBA MDS Dipper 3 automatically at three experimental sites.The results showed that the order of reduction in averaged soil salinity was 2.6 L/h > 2.2 L/h > 1.8 L/h > 3.2 L/h after the completion of irrigation for the 3-year cotton growing season.Therefore,the choice of emitter discharge rate is considerably important in arid silt loam.Usually,the ideal emitter discharge rate is 2.4-3.0 L/h for soil desalinization with plastic mulch,which is advisable mainly because of the favorable salt leaching of silt loam and the climatic conditions in the studied arid area.Maximum cotton yield was achieved at the emitter discharge rate of 2.6 L/h under drip irrigation with plastic mulch in silty soil at the study site.Hence,the emitter discharge rate of 2.6 L/h is recommended for drip irrigation with plastic mulch applied in silty soil in arid regions. | Sulitan DANIERHAN Abudu SHALAMU Hudan TUMAERBAI DongHai GUAN | 2013 | Journal of Arid Land2013，5，1： | 15 |
| 2 | Comparison of performance of statistical models in forecasting monthly streamflow of Kizil River,China显示文摘This paper presents the application of autoregressive integrated moving average(ARIMA),seasonal ARIMA(SARIMA),and Jordan-Elman artificial neural networks(ANN) models in forecasting the monthly streamflow of the Kizil River in Xinjiang,China.Two different types of monthly streamflow data(original and deseasonalized data) were used to develop time series and Jordan-Elman ANN models using previous flow conditions as predictors.The one-month-ahead forecasting performances of all models for the testing period(1998-2005) were compared using the average monthly flow data from the Kalabeili gaging station on the Kizil River.The Jordan-Elman ANN models,using previous flow conditions as inputs,resulted in no significant improvement over time series models in one-month-ahead forecasting.The results suggest that the simple time series models(ARIMA and SARIMA) can be used in one-month-ahead streamflow forecasting at the study site with a simple and explicit model structure and a model performance similar to the Jordan-Elman ANN models. | Shalamu ABUDU Chun-liang CUI James Phillip KING Kaiser ABUDUKADEER | 2010 | Water Science and Engineering2010，3，3： | 8 |
| 3 | 水稻控制灌溉下华东稻麦轮作农田N_2O排放模拟显示文摘基于田间小区试验,利用DNDC模型模拟了水稻控制灌溉下的华东稻麦轮作农田N_2O排放情况,分析了DNDC模型在该地区以及水稻控制灌溉条件下的适用性。结果表明,DNDC模型能较好地模拟控制灌溉稻田N_2O排放规律,模拟值与实测值的相关系数为0.79(n=39,p<0.001);同时能较好地模拟控制灌溉稻田N_2O排放通量与土壤水分调控及施肥的关系。但模型对土壤脱水程度的响应不够敏感,导致部分峰值出现时间稍有滞后。后茬麦田N_2O排放通量的模拟值多低于实测,模拟主峰值较实测值增大了14.96%(p<0.05),模拟次峰值比实测值减小了18.10%(p<0.05)。稻季、麦季及稻麦轮作期的N_2O排放总量的模拟值与实测值的相对误差分别为5.86%、-20.17%(p<0.05)和-4.97%,可见,DNDC模型能较好地模拟控制灌溉稻田N_2O排放总量,但明显低估了后茬冬小麦田的N_2O排放总量,稻麦轮作农田N_2O排放总量的模拟值和实测值总量相差不大。因此,DNDC模型可以用来模拟华东地区控制灌溉稻田N_2O排放,但不能准确地模拟后茬冬小麦田的N_2O排放。 | 侯会静 Shalamu Abudu 陈慧 杨士红 | 2016 | 农业机械学报2016，47，12： | 8 |
| 4 | Application of snowmelt runoff model(SRM) in mountainous watersheds:A review显示文摘The snowmelt runoff model (SRM) has been widely used in simulation and forecast of streamflow in snow-dominated mountainous basins around the world. This paper presents an overall review of worldwide applications of SRM in mountainous watersheds, particularly in data-sparse watersheds of northwestern China. Issues related to proper selection of input climate variables and parameters, and determination of the snow cover area (SCA) using remote sensing data in snowmelt runoff modeling are discussed through extensive review of literature. Preliminary applications of SRM in northwestern China have shown that the model accuracies are relatively acceptable although most of the watersheds lack measured hydro-meteorological data. Future research could explore the feasibility of modeling snowmelt runoff in data-sparse mountainous watersheds in northwestern China by utilizing snow and glacier cover remote sensing data, geographic information system (GIS) tools, field measurements, and innovative ways of model parameterization. | Shalamu ABUDU Chun-liang CUI Muattar SAYDI James Phillip KING | 2012 | Water Science and Engineering2012，5，2： | 7 |
