沼泽化草甸

在实施天然草原退牧还草示范工程的青海省玉树县上拉秀乡进行了3年禁牧封育退化草地的观测，研究了禁牧封育对高寒草甸和高寒沼泽化草甸退化草地的改良作用。

The effect of enclosing and grazing prohibition on the improvment of deteriorated alpine meadow and the alpine swamp meadow was conducted .

降雨对三角洲内大多数土地利用类型的影响都较强烈，相关系数在0.65-0.85之间，其中对沼泽化草甸的影响最大，相关系数达到0.829，随降雨的增加，沼泽化草甸增加趋势最明显。

Rainfall had great impacts on the majority of land use types in delta , the correlation coefficients are between 0.65-0.85 . Rainfall had the largest impacts on swamp meadow , the correlation coefficient is 0.829 . With the increase of rainfall , swamp meadow showed obvious increasing trend .

种子雨与植被之间关系的量化，可以对退化草甸在长期封育之后的演替方向或沼泽化草甸向典型草甸的演替方向做出准确预测。

To quantify the relationship between seed rain and standing vegetation can help us predicting the succession direction of degraded meadow following long-term enclosure or shift from swamp-to typical-meadow .

结果表明：地上生物量，地上碳、氮库，土壤碳、氮库分别递增顺序为耕地<弃耕地<沼泽化草甸。

The results show that the dynamics of total aboveground biomass , aboveground carbon and nitrogen pools , carbon and nitrogen pools in soils are similar , cultivation < abandonment < marsh meadow .

同时，采用碱液吸收法对该草原群落和一个沼泽化草甸群落的土壤呼吸进行了比对测定，比较在不同生境下土壤呼吸速率的差异。

Soil respiration rate was measured by alkali absorption method in both the steppe community and a meadow community concurrently in order to compare their differences in different habitats , and then tried to figure out the causes .

而弃耕5年后，地上生物量恢复到原始水平的71.61%，土壤碳、氮库分别达到沼泽化草甸的62.6%和50.32%；

However , after abandonment for 5 years , total aboveground biomass reaches 71.61 % of the initial level , pools of carbon and nitrogen in soils restore to 62.6 % and 50.32 % of the meadow-boggy soil respectively .

有毒植物在亚高山草甸草地中分布最多，有157种，其次是亚高山灌丛草地、高山草甸草地、高山灌丛草地和高寒沼泽化草甸草地。

These toxic substances most occurred in the plants distributing sub-alpine meadows , which total 157 species and then secondly in the plants distributing in sub - alpine scrub meadow , alpine scrub grassland and cold alpine paludification meadows .

青海湖地区主要草地类型包括高寒草原、高寒草甸、高寒荒漠、沼泽化草甸等，其中高寒草原和高寒草甸所占的面积最大，在畜牧业经济和生态保护中也最为重要。

Alpine steppe 、 Alpine meadow 、 desert steppe 、 Wetland meadow is mostly grassland types in Qinghai lake area , the area of Alpine steppe and Alpine meadow is the largest , they is important in economy of animal husbandry and ecological protection .

河流量与水体/草本沼泽、沼泽化草甸和盐碱地呈正相关，与草地、林地和稀疏草地/林地呈负相关。

River flow and water body / herb marsh , swamp meadow , saline and alkaline land was positively correlated . River flow and grassland , woodland , sparse grassland was negatively correlated .

海拔在4300米以下的高原山区和高原坝区的沼泽、沼泽化草甸、高山亚高山草甸适宜作为发展牧业的草场资源；

Swamp , swampy grass marshland , high and semi-high mountain grass marshland types in the plateau mountain areas and plains with altitude below 4300m , are suitable for developing into grass resources for livestock farming .

从湖心至丘顶的垂直分布规律表现为水生植被→沼泽植被→沼泽化草甸→亚高山草甸→亚高山灌丛。

The vertical distribution regularity is as follows : aquatic vegetation → moor vegetation → swampy prata vegetation → subalpine meadow → subalpine shrub from the center of lake to the hilltop .

受光谱分辨率和空间分辨率的影响，能从图像上提取到信息的湿地类型有河流、河漫滩、湖泊、水田、沼泽、草甸、沼泽化草甸。

Limited by spectrum resolution and spatial resolution , we were only able to derive the categories of river , flood plain , lake , paddy field , swamp , grass marshland and morass from RS images .
