摘要为了解决荒漠半荒漠风沙区草地退化问题，通过对盐池县草地资源利用现状的分析，结合畜牧业发展的要求，借鉴新疆草地生态置换的方法，提出了盐池县要实现生态环境的改善和草地的永续利用，应坚持走建设草地生态保护区，围栏封育退化草地，高效利用基本牧场，用部分中低产田和有灌溉条件的农田置换严重退化的草地等方式相结合的道路。
2.Any of various songbirds of the genus Sturnella of North America, especially S. magna, the eastern meadowlark, and S. neglecta, the western meadowlark, having brownish plumage, a yellow breast, and a black crescent-shaped marking beneath the throat.
草地鹨一种产于北美洲的草地鹨属鸣鸟，尤指东部草地鹨的东美草地鹨，和西部草地鹨的西美草地鹨，长有深褐色羽毛，胸部为黄色，喉部下面有黑色新月形标记
3.Using NOAA/AVHRR data observed at Urumqi,Fukang,Altai,Balikun monitoring station during 1992～1994,the annual variation characterisitics was studied and the differences of grass yield and AVHRR vegetation indices were compared.The grass yield and AVHRR vegetation indices had annual variation characteristics that their values were low in spring and then increaseed,the maximum values reached in summer and then they decreaseed.The AVHRR vegetation indices can reflect the changes of grass yield of different types of natural grasslands,therefore it is possible to classify different types of natural grasslands and to determine the optimum period of interpretation through AVHRR vegetation indices.The AVHRR vegetation indices can be used to monitor the grass yield and to predict the maximum yield because the AVHRR vegetation indices vary with grass yield in different seasons and from year to year.
采用1992～1994年牧草产量资料、NOAA/AVHRR资料分析了北疆主要天然草地牧草产量与卫星植被指数的变化特征，结果表明牧草产量和卫星植被指数都存在周年变化，用卫星植被指数可以较好地反映牧草产量的年际变化和不同类型天然草地的牧草产量差异，但对草甸草地和草原草地的监测效果比对荒漠草地监测效果好，利用实测资料建立了新疆北部主要天然草地牧草产量遥感监测模型。

5.grassland ecosystem. According to the different vegetation types in Tian Zhu county of Gan Su province, three representative alpine shrubs grassland samples were selected for research. ,that was sample 1.Rhododendron fruticosa shrubs,sample 2.Salix cupularis fruticosa shrubs and sample 3. Dasiphoru fruticosa shrubs,all of which were common pasturage.
根据甘肃省天祝县东祁连山高寒灌丛草地的不同植被类型，本文选取三种具有代表性的高寒灌丛草地植被类型，样地1杜鹃高寒灌丛(Rhododendron fruticosa shrubs)草地，样地2高山柳高寒灌丛(Salix cupularis fruticosa shrubs)草地，样地3金露梅高寒灌丛(Dasiphoru fruticosa shrubs)草地，各样地均为公共牧场。
6.TM images of study area in 1994 and 2001 are chosen as the basic data, using GIS technique, the situation of grassland utilization and grassland degradation is firstly analyzed.
摘要以1994年和2001年的TM图像作为原始数据，在GIS技术支持下，对西藏自治区那曲县的草地资源利用和草地退化的现状进行了分析，并在此基础上探讨了草地退化强度变化和草地型动态演替的规律。
7.According to the first national survey of grassland resources, the variety of grassland in Tibet ranks first among all provinces and autonomous regions. Of the 18 types of grassland in the country, Tibet has 17.
根据全国首次统一草地资源调查，西藏拥有草地种类居全国各省、自治区之首，在全国18个草地类中，西藏就占有17个草地类。
8.According to the compensatory growth regularities of sward and Stipa grandis , the optimal intake rate of steppe dominated by Stipa grandis should be in 45%～55%, and relative stocking rate was 3.5 sheep/summer and autumm/hm+2.
