摘要: Abstract Human activities pose severe threats to ecosystems. As the Earth’s third pole, Tibetan Plateau (TP) provides various ecosystem services for human beings, including water resources nearly 40% of world’s population. In this study, four categories pressures on environment were analyzed firstly and then summed cumulatively map influence intensity (HII) in TP 1990–2010 at county 1 km scales. Subsequently, HII characteristics within valuable regions retention biodiversity conservation analyzed. The results showed that was low overall. eastern southeastern central part Tibet Autonomous Region saw high HII. For 1990–2010, scale mean increased by 28.43%, which is much greater than global level 9% 1993–2009, suggesting it provided may face with more threats. increase mainly observed northeastern TP. Rapid during detected, especially former. obtained temporally-consistent datasets will be conducive related decision making.
