- 摘要:
- 分别采用1973年、1993年和2010年三期遥感影像，基于植被指数与植被覆盖度之间的关系建立植被覆盖度指数模型，运用遥感与地理信息系统技术对施秉云台山地被覆盖度进行等级划分，并对其近40 a的动态变化过程进行研究。结果表明：云台山地区植被覆盖度总体呈现退化态势，但是局部地区植被覆盖情况有改善趋势；1973—2010年间，云台山核心区覆盖度等级明显高于周边地区，但是这一优势在不断衰退；核心区植被覆盖度变化幅度小于周边地区，核心区植被覆盖度比周边地区较为稳定，低等级覆盖度变化幅度大于高等级覆盖度；前20 a植被覆盖度主要以退化趋势为主，后20 a则呈现逐渐恢复态势；植被覆盖度变化趋势受当地经济发展模式和生态环境观念改变影响较大。
- Abstract:
- This paper adopted three periods of remote sensing images in 1973, 1993 and 2010, respectively, to establish the vegetation coverage index model based on the relationship between vegetation index and vegetation coverage, divided the grades of vegetation coverage using the technology of RS and GIS, and studied the process of dynamic change in recent 40 years. The result shows that vegetation coverage generally degraded Yuntai mountain area, but it showed the improving tendency in the local area; the grade of coverage in the core area was much higher than that in the surrounding area in the period from 1973 to 2010, but this advantage was declining; the change in the core area was less than the surrounding area, and the coverage change of the lower grade was more significant than the high grade, the vegetation coverage in core area was more stable than the surrounding area, the change of lower level coverage was greater than the high level coverage; in the first 20 years, the vegetation coverage mainly presented the trend of degradation, but it was restored gradually in the recent 20 years; the economic development models and the concept of ecological environment played important roles in the trend of the vegetation coverage change.
