阿尔泰生态功能区植被的周期性变化及影响因素分析

针对植被与气候因子的分析多从研究区总体出发、缺少地域差异化研究的问题,本文提出了在不同地貌、坡度和植被类型区域进行植被覆盖度的时空分布特征及其影响因子分析研究的方法.该方法实现了植被在不同地理环境、不同植被类型中对气候因子响应机制的差异化研究.结果表明:1)植被覆盖度在平原和丘陵、坡度小于2°和大于15°区域递增趋势较...

Analysis of Vegetation Periodic Change and Its Influencing Factors in Altay Ecological Function Area

In view of the fact that the analysis of vegetation to climate factors is mostly based on the overall situation of the study area and lacks the research on the characteristics of regional differentiation,in this paper,a method is proposed to analyze the spatial and temporal distribution characteristics of vegetation coverage and its influencing factors in different landforms,slopes and vegetation types.This method realized the difference research of response mechanism of vegetation to climate factors in different geographical environments and vegetation types.The results show that:(1)the increasing trend of vegetation coverage is obvious in plain and hilly areas,and in areas with slope less than 2°and greater than 15°while the increasing trend of shrub vegetation coverage is obvious;(2)the response characteristics of vegetation to temperature and precipitation in different time scales and different geographical regions are inconsistent,or even opposite;(3)the response of different types of vegetation to temperature and precipitation is not consistent in April and August,but not obvious in other months.
