The study, which aimed at 100 heads of breeding cattle marketed per annual and which object was the grazing for the flock of shorthorn beef cattle on sown pasture in the ZYCBC system, indicated that by making full use of pasture growth quantity and nutrient substance on sown pasture and supplementing mixed concentrate in late of breeding cow pregnancy, the number of beef cattle grazed in the while year had get to 375 heads, for the forage was budgeted and dynamic balance between the forage and beef cattle was gained and kept. It needed 642. 67t DM of forage annually in the system, 764t DM of which was provided by the sown pasture and 339t DM of which by forage crop land.

以ZYCBC系统短角肉牛群人工草地放牧饲养为对象，以年出栏100头种牛为目标，进行饲草预算和草畜动态平衡，充分利用人工草地的牧草生长量和营养物质，母牛怀孕后期适当补饲混合精料，全年牛群饲养量达375头，系统全年共需饲草642.67tDM，其中人工草地提供764tDM，饲料地提供339tDM。

The result indicated that: with the change of ecological factors and intensification of human activities,strong stability of grassland community structure of the local alpine meadow type along the highway in this region was found,proportion of medium xerophilous、rhizomous grass increased;alpine grassland community had relatively low stability,grassland community successed naturally to adapt to the new environment;...

结果显示：随着生态因子发生变化和人类活动的加剧，该区公路沿线高寒草甸类草地群落结构表现出了较强的稳定性，中旱生耐旱的根茎型禾草比重有所增加；高寒草原植物群落稳定性相对较差，草地群落为适应新的生境而发生了自然演替；沼泽化草甸亚类草地植物群落中群落伴生种的种类增加，优势种嵩草属植物在群落中的比重有所下降。

Spatial conversion: The spatial conversion mostly occurred between cultivated land and settlements.Additionally, the increase of land for urban construction includes rural settlements which assimilated by urban expansion.The fraction of xerophilous grassland increase mainly converted from un\|irrigated cropland, shrub forest mainly converted to xerophilous grassland, and bottom land mainly converted to water body.

3空间转换：以农田和聚落之间的转换为主，另外城镇建设用地的增加包括其扩展融入的农村聚落等；典型草地的增加主要来自旱地；灌丛减少主要是转变成典型草地，其次是转变成灌丛草地；河湖滩地减少主要是变为内陆水体，再是转变成水浇地。

The evolvement of grazing systems in rangeland was introduced, 290 herdsmen's households of six Sumu in Hunshandake sandy rangeland was investigated by random surveyes of households and autoptical investigations, and then different kinds of grazing systems and the management behaviors were analyzed.

在阐述草原牧区草地放牧制度演变的基础上，采用基于随机抽样的入户调查和实地考察的方法，对位于浑善达克沙地的6个苏木290个牧户进行了调查研究，分析了牧户草地放牧制度的不同类型以及草地利用中的经营管理行为。

The results show that, firstly, Stellera chamaejasme L, which rely on their developed axial root system in the 10～40cm soil layer to occupy the competitive priority of volume, length, surface area and so on, in the case of their adaptive faculty to poor surroundings resulting from fruit picking, trampling and overgrazing as well as with the phenomenon of restrained growth among various plants, gradually become the dominant plant in the herbaceous community; secondly, this kind of degraded grassland has not displayed any general characteristic of degradation such as surface exposure, accumulative quantity of vegetation reduced, water loss, soil erosion and so on, therefor, it should be dealt with distinguishingly; thirdly, if"Stellera chamaejasme L Killer"and"Oxytropis ochrocephala Killer"invented by CAS are taken advantage of respectively in the bloom period of Stellera chamaejasme L and at the beginning of florescence of Oxytropis ochrocephala bunge by ultra-low volume spray of 1. 05L/hm〓 and 1. 35～165L/hm〓 dosage separately, the death rates of poisonous herbs may achieve above 95% and 92% correspondently; fourthly, this technology with the characteristics of high work efficiency, exclusive selectivity and convenient operation, is safe to non-target plants and other animals, and has no toxic or side-effect to environment; furthermore, an execution of"Stellera chamaejasme L Killer"spray and a two-year grazing prohibition can be effectively applied on degraded grasslands of"Weed and Poisonous plants Type".

结果表明：狼毒凭借发达的轴根系在10～40cm土层中形成的体积、长度、表面积等竞争优势，以及对采食、践踏、过度放牧所形成的不良环境的适应能力和异株克生现象的存在，逐步成为草群中的优势植物；毒杂草型退化草地没有表现出地表裸露、植物蓄积量减少、水土流失等一般性退化特征，对该类草地的治理应区别对待；应用中科院研制的'灭狼毒'和'灭棘豆'分别在狼毒盛花期和黄花棘豆初花期，以1.05L/hm〓、1.35～165L/hm〓的施用量超低容量喷雾，毒草的死亡率可达到95％、92％以上；该技术具有工效高、选择性专一、灭效高、操作简便，对非靶标植物和其它动物安全，对环境无毒副作用的特点；采用喷施'灭狼毒'+短期禁牧措施，可以有效治理毒杂草型退化草地。

The relationship between weed invasion and intensity was analysed on sown pasture mixed by whiteclover and perennial ryegrass,and the preliminary results were that 1the number of invasive weeds ismainly dependent on grazing intensity;2the trend of species diversity was successively increase-decrease-increase when the grazing intensity is increase;3 principal invasion weed species are Lysimachiahemsleyana, Eragrostis nigra, etc,8 species;4the sown pasture in question is pioneer stage of the recoverysucce...

本文分析了白三叶草十多年生黑麦草混播人工草地上杂草入侵与放牧强度之间的关系，得出如下初步结论：1）杂草入侵的种数主要决定于放牧强度；2）α物种多样性随放牧加重而有增－减－增的趋势；3）入侵的主要杂草种为点腺过路黄等8个种；4）所论人工草地都处在恢复演替的先锋阶段，因而草地退化的进程还是能予以遏制的。

Expounded the biotic ecotype and nutrient analyses of cultivated leguminous grasses in Keeqin Meadow, scientific basis is provided for leguminous grasses' cultivatting widely and gilled s owing to build a good quality and high output grnssland.

本文着重对科尔沁草地适宜栽培的主要豆科牧草的生物生态学特性和饲用特性进行了阐述与评价，并对主要豆科牧草营养成分做了分析，为科尔沁草地大面积栽培及补播豆科牧草，建立高产优质人工草地，利用豆科牧草资源提供科学依据。

Soil moisture content varied abruptly in the ecotone zone, hut presented linear distribution in both grassland zone and farmland zone. The average soil moisture content in grassland was about 1 gg^(-1) higher than that in farmland, which was mainly caused by the decreased capillary moisture capacity of farmland.

其中农田－草地复合功能区的土壤含水量变化剧烈，而草地功能区与农田功能区内土壤水分基本呈线性分布；草地生态系统土壤平均含水量比农田高约1 gg^(-1)，这主要是由于草地开垦为农田后风蚀等作用而引起的土壤毛管持水力下降所致。

The paper supposed five different land use scenarios, scenario1: most of the land use is forest and grass, scenarios 2: most of the land use is forest, sparsely forest and grassland, scenarios 3: the real land use of the region of interest, scenarios 4: most of the land use is range grass, sparsely forest and grassland, and scenarios 5: most of the land use is range grass.

本文假设了5种不同情景下的土地利用类型，分别设置为5种不同的情景：情景1为林地和草地为主的土地利用类型，情景2为林地、疏林地和草地为主的土地利用类型，情景3为研究区现有土地利用情况，情景4为裸岩、疏林地和草地为主的土地利用类型，情景5为裸岩为主的，少量草地的土地利用类型，其中5种情景类型中的水域量始终保持不变。
