禁牧

同时发现禁牧改变土壤N转化进程，提高NH4+-N比例，降低相对硝化速率。

Meanwhile , it was found out that the N transformation procedure in the soil was altered by grazing prohibition , which increased NH ~ + _4-N proportion and decreased the relative nitrification ratio .

受草场质量、到草场的距离等因素影响，不同子流域内禁牧的机会成本是空间异质的。

Spatial heterogeneity of opportunity costs for grazing prohibition exists in each sub-basin due to grassland quality and access to grasslands .

此外，禁牧明显提高了土壤有机质数量和离子交换能力，降低土壤pH值，促进矿质元素分解转化，增加速效养分含量。

In addition , forbidden grazing significantly improved the quantity of soil OM and CEC content , lower soil pH , promoted mineral elements into decomposition , increase available nutrient content .

氨态N、氨基酸N、酸水解N的绝对量均是禁牧区大于放牧区，但占全N的比例二者无显著差异。

Absolute value of ammonium N , amino acid N , acid hydrolyzed N was higher in ungrazing sites than that in grazing sites , but the proportion to total N didn 't show significant differences .

荒漠牧草区年净第一生产力的空间分布有很大的差异，禁牧区牧草的年NPP相对非禁牧区的NPP较大，这一结论与地面观测结果相一致，NPP估算值平均误差为12.6%。

In the desert area spatial distribution of the annual NPP varies greatly and the NPP in the grazing-prohibited area is higher than that in the grazing area , and this agrees with the result in the field observation . The average NPP error is 12.6 % in the estimation .

并对未禁牧群落（退化群落）、禁牧7a的群落和禁牧20a群落的8种主要植物叶的解剖结构特征进行比较研究，以探讨植物叶结构对禁牧的响应。

Eight predominant plants were collected from unfenced community ( degenerated community ), community fenced for 7 years and community fenced for 20 years . Leaf anatomical structures were compared to reveal the responses of plant leaf structures to grazing prohibition .
