Persistence of grazing mixed pasture has been a key issue in environment conservation and sustainable utilizing of resources in karst region. Under moderate grazing with Corriedale sheep, the productivity and botanical composition of Trifolium pratense mixtures were studied over a 20-year period in karst region of southwest China. Four mixtures consisted of Trifolium pr...
用考力代绵羊轮牧，在牧前和牧后草地现存量(干物质，DM，drymatter)分别为1800~2500(草层高15~18cm)和900~1200kg·hm-2(草层高3~5cm)的适度放牧利用条件下，对亚热带最常见的豆科牧草红三叶与禾本科牧草的两两混播草地的群落生产力和持久性开展长期研究。20年的结果表明：适度放牧利用下，群落地上总生物量长期稳定，各组合间差异不显著，总盖度20a后仍高达97%以上；适度放牧有利于牧草的生产力持久性，红三叶、鸭茅、多年生黑麦草和黑穗画眉草都在群落中长期存在；群落净产量和持久性是尺度依赖的，群落长期净生产力以红三叶+鸭茅的最高(DM产量353.3g·m-2·a-1)(P.05)，对杂草侵入的抵抗力最强，而前10a红三叶+多年生黑麦草有很高的净生产力DM产量449.8g·m-2·a。。。

With a study of plant community succession on 5 stocking rates,herbage utilizational efficiency and risk-benefit balance,it is suggested the sustainable development should follow:(1)no degradational principle of rangeland,(2)the maximum herbage utilizational efficiency,(3)the risk-benefit balance,When stocking rate was no more than 2.67 sheep/hm2,the proportion of grasses and plant biodiversity index and evenness were increased based on Artemisia frigida and short-grass rangeland.
草地畜牧业可持续发展的三大生物经济原则为草场不退化原则、最大生物学效率原则和风险-利润权衡原则：(1)草场不退化原则。在冷蒿小禾草退化草原上，暖季期间1.33～2.67羊/hm\+2的放牧率下可使其发生恢复演替，禾草的比例增大，植物多样性指数和均匀度指数均有所提高，从而达到利用式改良的目的；相反，若继续重牧或过牧，放牧绵羊喜食的植物种类将进一步减少，植物多样性指数也有所降低。

Nine wethers selected from a group at 2-years-old of age were fed with fresh mixtures of Leymus chinensis (30%), Cleistogenes squarrosa (20%) and Artemisia frigida (50%) in known proportions and amounts for 14 days. Artificial QSM capsules were dosed during the experiment. The samples of herbage and feces were collected daily for 7 days and dried for analysing the n-alkane concentration by a gas chromatography. The results showed that there was a difference in concentration of n-alkanes among 3 species forages, and fecal recoveries of n-alkanes linear increased with increasing carbon chain lengths.
于2004年秋季在中国科学院内蒙古草原生态系统定位研究站用不同放牧演替阶段的优势植物羊草、糙隐子草和冷蒿按一定比例混合组成日粮，饲喂9只2岁羯羊，每只羊投喂一粒QSM胶囊，试验期内每天记录绵羊实际牧草采食量、采食成分和排粪量，利用气相色谱分析牧草和粪样的链烷含量，应用链烷技术测定绵羊的排粪量、不同牧草采食比例和总干物质采食量，并与实际值进行比较。
