摘要
位于滇东北的乌蒙山自然保护区,境内地形地貌比较平缓,降水较充沛,蒸发量小,湿度大,植被丰富。保护区地带性土壤有:黄棕壤和黄壤;非地带性土壤有紫色土和沼泽土。四个土类均呈强酸性反应。黄棕壤、黄壤、紫色土的全量养分和水解氮、速效钾都十分丰富,但速效磷含量低;沼泽土的有机质、全氮、水解氮、速效磷含量较高,而全磷、速效钾含量低。保护区植被盖度大,土层深厚,区内水土流失不严重,但在外围区域,由于人类活动的影响或地质危害,滑坡、水土流失较严重。总之,各相关部门应采取积极的保护措施。
Wumengshan Nature Reserve is located in the northeastern part of Yunnan province,China,with gentle topography & landform,abundant precipitation,less evaporation,higher humidity and rich vegetation.Zonal soils in the reserve include yellow-brown soil and yellow soil.Non-zonal soils include purple soil and bog soil.The four soil types show strong acid reaction.As for yellow-brown soil,yellow soil and purple soil,total nutrient,available nitrogen and available potassium are all abundant except available phosph...
