新疆按灌溉分区划分2009年灌溉水利用系数。一、指标应用范围1表21是各县区域引输水自流灌区灌溉水利用系数指标，可用于县级以下区域水资源利用、灌溉用水、农业节水等规划设计、灌溉管理查用。2表22是各县区域井提水自流灌区灌溉水利用系数指标，可用于县级以下区域水资源利用、灌溉用水、农业节水等规划设计、灌溉管理查用。3表23是农业高效节水灌区灌溉水利用系数应用指标，可用于高效节水灌区水资源利用、灌溉用水、农业节水等规划设计、灌溉管理查用。4表24是引输水、井水自流灌、高效节水灌溉工程现状2009年综合灌溉水利用系数水平。5表25是按灌溉分区划分灌溉水利用系数，主要是反映灌溉分区内现状2009年灌溉水利用系数水平。 二、技术指标注释1引输水自流灌区，指明渠引输水方式进行常规自流灌溉的灌区，不包括机电井灌区。该灌区包括：渠道水利用系数（含有防渗渠类型；土渠道类型）；渠系水利用系数（干、支、斗、农四级渠道）。2渠道防渗，指防渗渠道总长度与未防渗渠道总长度之比率。3田间水利用系数，指田间作物用水量与末级农渠配出水量之比率。4灌溉水利用系数，指田间作物用水量与引输水首部（渠首或某级供水处）配出水量之比率。5机电井提水自流灌区，指以机电井提水为水源进行常规自流灌溉的灌区，该灌区包括：渠道水利用系数（含有防渗渠类型；土渠道类型）；渠系水利用系数（斗、农两级渠道）。6农业高效节水灌区，指田间以喷灌（自压或加压式半固定喷灌，加压式喷灌机或移动式喷灌等）、微灌（自压或加压式微喷、滴灌、膜下滴灌、地下渗灌等）、低压管道输水灌溉（自压、加压式管道输水灌溉）的灌区。三、指标应用说明1表21使用方法：表中“综合类防渗渠道”、“未防渗类土渠道”两栏中，以及“引输水利用系数”中的“田间水”数据，是经测算分析得出相对稳定的基本常数。表中“渠道防渗（%）”，以及“引输水利用系数”中的“渠系水”和“灌溉水”，是以“渠道防渗（%）”数据为基础计算分析得出的，它是一个动态参数。引输水灌区灌溉水利用系数，是灌区干农四级防渗渠系水利用系数f干农和干农四级未防渗土渠渠系水利用系数t干农，与灌区当年干农四级防渗渠道长度占总长度比率fs的权重值。基本公式如下：灌溉 = f干农×fs + t干农×（1- fs） ×田间水式中 灌溉灌区灌溉水利用系数加权值；f干农灌区干农四级防渗渠系水利用系数；fs灌区干农四级防渗渠道长度占总长度的比率；t干农灌区干农四级未防渗土渠的渠系水利用系数；田间水灌区田间水利用系数。本表中基本数据是2009现状年成果，使用时，可根据灌区现状年干农四级防渗渠道长度占总长度的比率，即得出该年度的灌溉水利用系数。【应用举例】比如，和田市引输水灌区2009年干农四级渠道防渗率58.6%；查表21可知，防渗渠道干农四级渠道渠系水利用系数0.579；未防渗土渠干农四级渠道渠系水利用系数0.318；田间水利用系数0.896。则本灌区灌溉水利用系数：灌溉 = f干农×fs + t干农×（1- fs） ×田间水= 0.579×0.586 + 0.318×（1 0.586） ×0.896 = 0.422 如果，2010年该灌区干农四级渠道防渗率提高到60.6%，则灌区灌溉水利用系数为：灌溉 = f干农×fs + t干农×（1- fs） ×田间水= 0.579×0.606 + 0.318×（1 0.606） ×0.896 = 0.4272表22使用方法：井灌区灌溉水利用系数，井灌区斗、农两级渠道防渗率（x）与灌溉水利用系数（井溉）存在很好的相关性，其经验公式如下：井溉 = 0.001036 x + 0.657973本表中基本数据是2009现状年成果，使用时，可根据灌区现状年斗、农两级防渗渠道长度占总长度的比率，即可得出该年度的灌溉水利用系数。【应用举例】比如，和田市井灌区2009年斗、农二级渠道防渗率，查表22可知为47.4%；则本灌区灌溉水利用系数：井溉 = 0.001036×47.4 + 0.657973 = 0.707如果，2010年该灌区斗、农二级渠道防渗率提高到50.4%，则灌区灌溉水利用系数为：井溉 = 0.001036×50.4 + 0.657973 = 0.7103表23使用方法：农业高效节水灌溉灌区，经各灌区综合测算分析认为，高效节水灌区的灌溉水利用系数变化区间范围，总体在表23中反映的数据范围之内。在使用过程之中，可以按灌区所在灌溉分区内，选用表中参数区间范围值或是表中均值也可。4表24使用方法：灌区是由常规引输水自流灌溉，提水机（电）井灌溉，高效节水灌溉（喷灌、微灌、低压管道输水灌溉），形成灌区综合灌溉系统。因此，灌区综合灌溉水利用系数，应是上述多项灌溉水利用系数，以水量为加权而综合得出，基本关系式： 引灌w1 +井灌w2+ 喷灌w3 + 微灌w4 + 管灌w5 综合 = 5 wi i=1式中 综合灌区综合灌溉水利用系数；引灌常规引输水灌区灌溉水利用系数；井灌常规提水井灌区灌溉水利用系数；喷灌喷灌节水灌区灌溉水利用系数；微灌微灌节水灌区灌溉水利用系数；管灌低压管道输水灌区灌溉水利用系数；wi分别为引输水常规自流灌溉、提水井灌常规自流灌溉、喷灌、微灌、管道输水灌区的灌溉引用水量，万m3。【应用举例】比如，和田市灌区2009年现状综合灌溉水利用系数：查表21得，引输水灌区灌溉水利用系数0.422，常规灌用水量2.33万m3；查表22得，井灌区灌溉水利用系数0.707，常规灌溉用水量0.43万m3；查表23得，喷灌区灌溉水利用系数0.806，喷灌用水量0万m3；查表23得，微灌区灌溉水利用系数0.867，微灌用水量0万m3；查表23得，低压管灌区灌溉水利用系数0.792，灌溉用水量0.12万m3则本灌区综合灌溉水利用系数： 0.422×2.33 +0.707×0.43+ 0.806×0 +0.867×0 +0.792×0.12 综合 = （ 2.33+0.43+0+0+0.12 ） = 0.484本表中基本数据是2009现状年成果。使用时，可根据需测算年度的渠道防渗率，查用表21表23进行换算，即可得测算年综合灌溉水利用系数。5表25使用方法：查表24可得出某县域灌区某年度的灌溉水利用系数值；由当地灌区统计年报查出某县域灌区某年度的农业引用水量值；按水量加权方法得出“二级分区”、“一级分区”内的灌溉水利用系数。【应用举例】比如，“北疆塔额盆地区”灌溉分区2009年现状灌溉水利用系数：二级分区：山间盆地区1为：2.36×0.498+2.09×0.495+1.08×0.590灌溉水利用系数灌溉 = = 0.5152.36+2.09+1.08一级分区：北疆塔额盆地区为：2.36×0.498+2.09×0.495+1.08×0.590+0.72×0.545灌溉水利用系数灌溉 = 2.36+2.09+1.08+0.72= 0.518本表中基本数据是2009现状年成果，使用时，根据表24中某年度测算值，即可得出该年度灌溉分区灌溉水利用系数。表21 新疆 引输水自流灌区
