The reference crop evapotranspiration(ET0) in Guanzhong region was calculated with the Penman-Monteith equation. The change characteristics of meteorological factors and ET0 over year were analyzed. The regressing relation between ET0 and geography factors was established. Space distribution of ET0 based digital elevation model was obtained. The water consumption model of main cropes was established using the crop cofficient method. The irrigation water requirement of main crop and it's space distribution based DEM under the different precipitation probability was obtained, which advanced the calculation precision of ET0 from spot scal to regional scal. The concept of water consumption under the irrigational scal was proposed. The water consumption model of different water user and model of groundwater balance based on the water consumption of Baojixia irrigation district was established. Which can refects the relation between water utilization, water consumption and change amount of groundwater resouces.
深入分析了关中地区气象要素的变化趋势，用Penman-Montainth 公式计算了参考作物蒸发蒸腾量（ET0），建立了ET0与地理要素的多元回归关系，获得了基于数字高程模型DEM的关中地区ET0的空间分布图；用作物系数法建立了关中主要作物生育期耗水模型，获得了主要作物在不同降雨条件下的灌溉需水，以及基于DEM的主要作物灌溉需水空间分布图，提高了作物蒸发蒸腾量由点到面尺度转换过程中的估算精度；界定了灌区尺度的耗水量的概念，包括用水耗水和非用水耗水，建立了灌区耗水量计算模型及基于耗水量变化的浅层地下水均衡模型，能较好地反映灌区引水量、耗水量及地下水蓄变量之间的内在关系。

Part II: In accordance with the meaning of Zhuang toponomys, summed up several factors strong associated with the spatial distribution of the Zhuang toponomy,including the altitude, distance to the central cities, and distance to traffic line, whether in the land of paddy soil or irrigation area, the slope and aspect.
第二部分：根据壮语地名的涵义，总结出了海拔高度，与中心城市距离，与交通线距离，是否靠近或在灌溉用地或水稻土范围内、山体坡度、坡向几个与壮语地名的空间分布存在相关性的因子，经过统计分析发现壮语地名和非壮语地名相比较而言在空间分布上具有这样的特点：聚居地海拔高，与中心城市距离远，拥有灌溉耕地的机会多，距离铁路近。

Due to food pressure, grain product in the western Jilin Province will be enhanced in the near future. Farmland areas in the area will be decreased slowly in the near future, but with the technique development of irrigation establishment, paddy areas and utilization amount of fertilizer and pesticides will be increased rapidly. So, the NPS pollution from farmland will be more serious. The main lakes in the areas such as Moon Lake and Qagan Lake have been polluted by N and P, and the content of salt in the Nenjiang River has been increasing since last 30 years. All of these show that the negative effects of NPS pollution in the area have been serious and should not be neglected by the scientific research and corresponding government management. To deal with the contradiction of agriculture development and water pollution, the trend of increasing paddy area and using amount of fertilizer, pesticide and herbcide in the western Jilin Province should be controlled. Also, the drainage of return flow from paddy should be controlled and return flow should be disposed with ecotechniques by use of the large areas of lakes and mires in the area. Through these measures, the quality of surface water could be protected and the degeneration of ecoenvironment in the area could be contained.
我国由于粮食压力，未来吉林西部的粮食生产还将进一步加强，随着种植业结构的调整，垦殖率会略有下降，但随灌溉设施的建设与完善，水田面积将进一步扩大，化肥、农药的用量还将快速增加，农业活动引起的非点源污染将更加突出，而研究区的主要湖泊月亮湖、查干湖目前已达中等富营氧化水平，嫩江水质的咸化趋势明显，因此农田非点源污染物的流失及其内流区外流化面积的增加对地表水体富营养化、咸化的作用愈来愈明显，农田非点源对地表水水质的影响已不容忽视，应引起社会的关注，为协调农业发展与水污染这一矛盾，吉林西部应遏制化肥、农药施用量增长过快和水田过度开发的势头，控制洗盐回归水的排放量，利用区内广泛分布的大量泡沼对农田径流和回归水进行生态处理，既保护了地表水的水质，又有利于生态环境的改善。
