The paper establishes a comprehensive evaluation model of meadow resources using the fuzzy mathematical method , and then applies the model to the dynamic evaluation of subalpine meadow in huapo , qinyuan county , shanxi 摘要应用多层次模糊综合评价方法建立草地资源的综合评价模型，对山西沁源县华城乡亚高山草甸植被利用进行动态评价。
With the decrease of soil humidity , the bacterial number decreases , while the fungal number increases generally . microbial biomass estimated by fluorescein microscopic counting the highest biomass of bacteria was appeared in august 高寒草甸土壤中纤维素分解菌纤维素分解菌的数量较少，随着土壤温度的变化纤维素分解菌的数量在每年的
Abstract : burrowing behaviors of the plateau zoko rs ( myospalax bailely ) in rel ation to soil hardness were investigated by using radio - telemetry at haibei alp i ne meadow ecosystem research station , qinghai , china 文摘:采用无线电遥测法在中国科学院海北高寒草甸生态系统定位站对高原鼢鼠的挖掘行为及其与土壤硬度的关系进行了研究。
The average of shannon - wiener diversity index was 1 . 5481 in typical steppe abandoned land , which was only 55 % of natural grassland , while it was 1 . 3492 in meadow steppe abandoned steppe 典型草原撂荒地shannon - wiener多样性指数的平均值为1 . 5481 ，是天然草地的55 ，草甸草原带撂荒地shannon - wiener多样性指数的平均值为1 . 3492 ，是天然草地的50 。
Cows graze along the fertile banks of the thames between newbridge , where the river begins winding between townless water meadows , to oxford , which has been the home of britain ' s oldest university since the 12th century 奶牛沿着新桥间富饶的泰晤士河岸吃草，泰晤士河从这里开始在无人居住的湿地草甸上蜿蜒流淌，奔向十二世纪以来就作为不列颠最古老大学驻地的牛津。
A known amount of lycopodium spores was added to each sample to calculate the concentration of pollen ( grains / gram ) . pollen was examined at magnifications of 100 + and 400 + and identified using modern pollen collections and published atlases P2 - 1 ：该亚带木本花粉的浓度达到了9 . 79粒克，而草本植物花粉的浓度相对于p1带有所下降，气候条件较好，植被为草甸草原。
The smallest one is alpine brush , it covers 0 . 87 % , 2 . 74km2 from the result we can find that landscape vegetation types are different . coniferous forest , alpine brush , steppe and desert are resource - environmental type . meadow is survival type 成因上，针叶林、高山灌丛、高山草原、山地草原、高山草甸、荒漠为环境资源型，栽培植被为引入型，无植被地段为干扰型。
