山地是地球上的三维地貌，具有明显的起伏和梯度，由于自然因素及其引起的人类活动随海拔和相对高度的变化而变化，山地的高梯度效应显现出来，也就是说，山地高梯度效应表现为自然因素和人文因素随海拔和相对高度的变化，是山地演化的综合效应横断山区是典型的山地河谷区，山区高梯度效应显著，其含义包括能量、降水、温度、气候、气候地貌、自然带、社会经济活动和居住等方面的高梯度效应，能量包括重力势能、山地高梯度效应研究是响应“21世纪全球化”的重要活动。高梯度效应研究是对山地复杂性研究的一种重要方法，对山地自然资源的利用、社会经济发展、生态建设和区域可持续发展具有重要意义。
Mountain regions were 3-D landforms on the earth,which have obvious undulation and gradient.Because the natural factors and their consequent human activities vary with elevation and relative height,the high gradient effects of mountain regions appear.That is to say,the high gradient effects of mountain regions exhibit the natural factors and human dimension changing with elevation and relative height.These are integrated effects of evolution in the mountain system.The Hengduan Mountains are the typical upland-valley areas,where the high gradient effects of mountain regions are notable.The meaning of the high gradient effects includes high gradient effect about energy,precipitation,temperature,climate,climatic landforms,natural belts,social and economic activities and habitation etc.The energy includes gravity potential energy,heat energy and biomass etc.Research on the high gradient effects of mountain regions is the important activities responding to the \!Global Change and Mountain Regions\" which is put forward by IGBP,IHDP and GTOS.The study on the high gradient effects is an important method to go through the complex research on the mountains.It has great significance in the use of natural resources in the mountains,social economy development,ecological construction and regionally sustainable development.
