treeline

Above the treeline take a grassy path leading steeply towards the summit .

过了林木线之后沿着长满青草的小道直通陡峭的顶。

Alpine Describing a BIOME ( regional community ) of plants above the treeline and below the snowline on high mountains .

高山的：描述在高山雪线以下的植物生物群系。

As the sun dipped below the treeline , I came across an imposing chestnut with a hollow at its base big enough for me to crawl inside to hide and wait , to listen for the seekers .

阳光在沿途的树木间洒落，我看到一株巨大的栗树，它的底部有个大洞，我爬进去藏在里面，等着听搜寻人员的呼唤。

Tree-growth in alpine treeline held a high-temperature and arid period , which was general period during 1920-1930 's in northwestern China , and the authors also found that it was the coldest and longest period during 1861-1878 in last 200 years .

西北干旱区中普遍存在的20世纪2030年代高温干旱期在这里也很显著，同时该研究也发现18611878年是近200年来的7月气温最低和最长的时段。

Net primary productivities of larch mixed forest and birch forest decreased sharply at treeline in comparison with lower altitudinal stands , whilst the ratio of root production was much higher than that of lower altitude . This made it profitable to take water and nutrients in soil .

树线地带落叶松混交林和岳桦林的净生产量也出现急剧降低，但根系生产量比例则较低海拔同类林分高，有利于对土壤中水分和养分的吸收。
