    "ds_abstract": "<p>选择青藏公路昆仑山—唐古拉山南坡段为研究区域，全长430km。研究区段的自然生态系统可以划分为高寒草原生态系统、高寒草甸生态系统、高寒沼泽湿地生态系统三大类型。</p>",
    "ds_source": "<p>主要分布于青藏公路沿线的西大滩至沱沱河一带海拔4100-5100m的地区，是研究区域分布最广、面积最大的生态系统类型，根据建群植物种的不同，可分为紫花针茅(Stipa purpurea)高寒草原、青藏苔草(Carex moorcroftii)草原、扇穗茅(Littledalea racemosa)高寒草原等。</p>",
    "ds_process_way": "<p>生态系统调查：采用样带调查方法，样带设置分三种情形，一是按主要生态系统类型分布区域划分研究分区，在不同生态系统分区沿垂直公路方向设置生态样带，二是在相同生态系统类型分区中，根据地貌单元变化部署样带；三是在同一个地貌单元内，依据人类工程活动干扰程度、冻土环境状况以及生态环境的主要变化形式等，部署不同样带。样带长度根据垂直方向植物群落分布与变化、人类活动干扰迹地分布情况等设置为10-20km，在每条样带上依据地貌形态、人类活动强度以及植物群落类型与结构的梯度变化部署样方点，在每点沿不同方向设置100cm×100cm 样方8-12个。</p>",
    "ds_quality": "<p>采用TDR时域反射仪测定土壤不同深度水分含量；在每个样方点于0-100cm 深度内分层采集土壤样品一组。采用EKKO100地质雷达探测仪，在每个样方带上以及平行公路方向连续采样1-1.5km，以查清冻土上限深度。</p>",
