4组成连续放牧区羊食物的植物种类丰富，粗蛋白、粗脂肪、粗灰分含量高于轮牧区，粗纤维含量低于轮牧区。

The composition plants of the sheep diet was more abundant in CO than in RG . The crude protein , crude fat of diet were higher in CG than RG .

禁牧区植物种群重要值高于自由放牧区，说明禁牧区较自由放牧区群落具有较高的稳定性及对环境具有较高适应性。

Compared with the free grazing area , the plant population important value were highest in banning grazing area , indicating the plant community employed better stability and adaptability to environment .

当雨季相继光临苏丹&这一非洲最大国家的不同地区的时候，也是部落间为自己牛群和其他牲畜抢占最好放牧区激烈之时。

As the rainy season arrives in different parts of Africa 's largest country , so the traditional competition for the best grazing areas for cattle and other livestock becomes more intense .

像西北的不少地方，应该下决心以种牧草为主，发展畜牧业。怀俄明州是一个天然的放牧区，那里的牧草是吃不完的。

For instance , many areas in northwest China should concentrate on growing forage grass in order to expand animal husbandry . Wyoming is a natural grazing country and cannot be eaten out .

轮牧条件下的土壤表层硬度及容重低，土壤含水率和孔隙度高，不同土层的氮、磷、钾及有机质含量轮牧区比自由放牧区高，土壤保水保肥性能好。

In the rotational grazing the surface soil hardness and bulk density were decreased , soil moisture and porosity were increased , soil nitrogen , phosphorus , potassium and organic matter were high .

划区轮牧区的优势种的密度、高度、盖度以及重要值在两年均高于自由放牧区（P<0.05）。

The density , height , coverage and importance value of dominant species in plant community in rotational grazing were higher than that in continuous grazing ( P < 0.05 ) in the two years .

鹅绒委陵菜叶数、匍匐茎长度、地上生物量、匍匐茎生物量、开花数、生殖生物量、有性繁殖效力及营养繁殖效力在放牧区显著高于不放牧的对照区。

P. anserina presented higher in its leaf number , stolon length , aboveground biomass , stolon biomass , flower number , reproductive biomass , sexual reproductive effort and vegetative growth effort with grazing than without grazing .

划区轮牧区的群落现存量及优势植物羊草的现存量较自由放牧区高，两个放牧制度的产量高峰期滞后于对照区。

The standing crop of community and Leymus chinensis in the rotational grazing area were higher than that in the continuous grazing area , the peak time of stand crop in two grazing systems which compared with check plot were lagged .

主要研究成果如下：1.沙质草地放牧区主要植物高度、盖度、地上现存量和物种丰富度高于高平原草地放牧区。

The main results were shown as follows : 1 . The height , cover , above present biomass , richness , edible forages , and diversity of the community in grazing plot of the sand grassland were lower than that of the high plain grassland .

在进行规划时，将园区划为高效农业示范区、放牧区、生态休闲区、生态林游憩区、特色养殖区、生态度假区、现代农业生产等七个功能分区。

The whole park is divided into seven functions in the course of planning , including high-efficiency agriculture demonstration areas , grazing areas , eco-recreation areas , ecological forest recreation areas , characteristic culture areas , ecological holiday resort areas and modern agricultural production zone . 4 .

主要植物种群的净初级生长量在不同放牧处理区存在着差异，从而表现出不同的补偿性生长趋势；

However , differences in compensatory growth were found in main plant populations , in which net primary productions were different in the two grazing systems .

各放牧处理区2003年同一时期的地上生物量均高于2004年，且牧草生长季节地上平均生物量及其年度变化之间的差异显著（P<0.05）。
