Analis presented in our 85 survey locations that were distributed in all counties on the Taiwan excluded the Taitung county, Hualien county, green island and orchid island. The altitude of P. analis habitats ranged from plain to the 400 m. The eleven types of habitats included bamboo plantation, windbreaks, orchard, dry riverbed, grassland, tea plantation, broadleaf forest, vegetable, paddy field, sugarcane field, and Arecae catechu showed the high diversity. The grassland was found in the highest ratio among 34 habitats and followed by the dry riverbed, which was found eleven sites.

The region in the altitude f rom 4400 to 4600 meters , which is mainly covered by alpine meadow and alpine swamp meadow , is st rongly degraded by the stock raising with it s influence radius of about 24 kilometers. The influence distance perpendicular to roads is also 24 kilometers , since road const ruction accelerates human2induced destruction to vegetation. Vegetation in shade aspect is rising due to the increase in precipitation , while vegetation in sunny aspect tends to be stable or degraded because of the enhancement in sunlight . Furthermore , the vegetation coverage is influenced by the groundwater level . In near riverbed fields , where the depth of groundwater is shallow , plant s can easily grow ; while in far riverbed fields , vegetation is prone to degrade due to drainage. The radius of river influence is 24 kilometers.
海拔4400~4600m的较低海拔地带退化最强烈,主要为高寒草甸与高寒沼泽草甸受牧业影响较大;牧业影响半径为24km;道路的影响范围为24km,道路的修建加速了人类对高原植被的破坏作用;阳坡植被呈现趋于稳定和退化的趋势,阴坡植被表现为增长的趋势,降水量增加是源区植被,尤其是阴坡植被变好的重要原因,而太阳光照增强是导致阳坡干旱和植被趋于退化的潜在原因;近河床区地下水位埋深较浅,植被生长具有稳定的地下水源;在远离河床的一定区域内,地下水易于疏干,植被易于退化,河流影响范围为24km。
