对云南高原环境演化研究的重要性及环境演变的初步认知

云南高原是我国四大高原重要组成部分之一，相比较而言，云南高原环境演化及其资源环境效应研究较零星，不够系统深入。对云南高原环境演变进行研究有助于解决云南高原环境演化的独特性和有助于地球系统科学的发展，有助于西部大开发的实施和脱贫致富与可持续发展。云南高原环境演化从第三纪的云南“准平原”形成后受云南运动（青藏运动B幕）的影响，使夷平原位移解体，现代地貌和水系格局逐步形成，由古季风气候控制转化为东南季风，西南季风共同交互影响，出现了生物多样性，生态环境多样性，资源多样性等多种特征，也影响到民族多样性，文化多样性等，使云南高原成为我国西南地区的“宝地”之一。

THE ELEMENTARY ACKNOWLEDGE ON THE IMPORTANCE OF ENVIRONMENTAL EVOLUTION OF YUNNAN PLATEAU

Yunnan plateau is one of the four plateaus in China.Comparatively,there are only a few researches on the environmental evolution and its resource environmental effects,and these researches are not deep enough.The research on plateau environmental evolution in the Yunnan will be beneficial to solving the problems of the uniqueness of Yunnan plateau and to the development of earth science,and will be beneficial to the implement of Great Development in Western Provinces of China and the sustainable development.After Yunan underwent the peneplanation in Tertiary its environmental evolution began from the Yunan movement occurring in late Pliocene which made the leveling surface displacement and disaggregated,then the modern landform and water system were formed gradually,and the environment controlled by the ancient monsoon changed alternating influence of south-east and south-west monsoons,then the biology diversity,environmental diversity and resource diversity came into being,and influenced the diversity of ethnicity,the diversity of culture.
