Adopt the mean of analyzing the factors which influence the output of the crops to quantity and determine the factors , assess the correlation among the grading factors in the units and calculate the point value of these factors ; determine the weigh value of the factors . ten factors , which are content of organic matter , thickness of soil layer , quality of soil , pickled degree of land , condition of irrigation and state of shelter belt , the degree of land " s leveling , central focus region ( focus region location ) , utilization method of soil , are chosen as grading index at last 本文采用因素法定量化评价各地块定级单元的相关性和权重性，最终选定了有机质含量、土层厚度、土壤质地、盐碱化程度、排水能力、灌溉保证率、防护林完整度、条田平整度、中心区位，土地利用方式等因子作为定级的指标，使用了加权加和因素法进行了的定级计算，逐步完成了农用地质量情况的评价，划分出了级别。
Water delivery has been run over 30 years . the main canal has the problem that the actual conveying capacity is very low now and the conveying capacity of the east - one main canal i only half of the design value , this lead to guaranteed real - time efficiency of the irrigation of the farmland recede greatly . the downstream has no water and crops were drought to death have been seen more times in the irrigation period , this lead to the contradictory between the upstream and downstream on water usage , moreover , the lower discharge capacity of the dry canal in irrigation period is the main cause of the actual irrigated area is only half of the design value 经过三十年的输水运行，目前干渠工程存在严重的输水能力低问题，其中东一干渠输水能力只能达到原设计的1 2 ，使农田的适时灌溉保证率大大降低，多次发生灌溉期下游见不到水而旱死庄稼的情况，造成上下游用水矛盾突出，而且灌溉期干渠过流能力偏小，是导致实际灌溉面积仅为设计值的1 3的重要原因。
According to the result of the overall planning of containable utilization of water resource of shandong province during the initial period of 21 - centrury and the planning of urban water resource of the south - to - north water transfer project of shandong province and combining with the situation of the south - to - north water transfer project and through ample investigation and analysis , the paper evaluates comprehensively the quality and quantity of water resource of shandong province and points out the mail existing problems in the development and utilization and management and analyzes and forecasts scientifically the supply and demand situation of water resource of shandong province at the situation of different planning level year and different guarantee rate and advances the basic thinking , aim , task and requirement for solving the shortage problem of water resource of shandong province through comprehensive and systematic analysis from six aspects including water resource development , utilization , harnessing , d istribution , save and protection according to economic and social continuable development ' demand to water 本报告根据《 21世纪初期山东省水资源可持续利用总体规划》和《山东省南水北调城市水资源规划》成果，结合南水北调工程情况，通过大量调查分析，全面评估了山东省水资源的质和量；指出了开发利用和管理方面存在的主要问题；科学分析和预测了不同规划水平年、不同保证率情况下的山东水资源供需状况；根据经济社会可持续发展对水的需求，从水资源开发、利用、治理、配置、节约和保护六个方面进行了全面系统的分析，提出了解决山东省水资源紧缺的基本思路、目标、任务和要求。
