摘要/Abstract

摘要： 以湖北省竹山县为研究区，运用RS和GIS技术，并借助空间叠加分析，研究区内植被覆盖度分别随不同地形因子变化的分布特征及相关性。研究结果表明：① 研究区植被覆盖度整体情况良好，以高覆盖度为主，占比为80.45%。② 植被覆盖度随高程的升高呈增加趋势，在高程大于2 000 m时达到最大值，其值为91.99%；植被覆盖度随坡度增大呈先增大后减少趋势，在35°~45°坡度带达最大值；在坡向上，阴坡植被覆盖度整体稍高于阳坡。③ 不同植被覆盖度与各地形因子级的相关性强度不同,对于各级植被覆盖度，坡度和坡向对其影响明显高于高程，植被覆盖度越高，坡度和坡向两者对其影响越明显;高程与各级植被覆盖度的相关性无明显的规律。

Abstract: Taking Zhushan county, Hubei Province as the research area, the distribution characteristics and correlation of vegetation coverage with different topographic factors were studied by using RS and GIS technology and spatial superposition analysis. The research results showed that the overall vegetation coverage of the study area was good, dominated by high coverage, accounting for 80.45%. The vegetation coverage increased with the elevation and reached the maximum value of 91.99% when the elevation was greater than 2000 m. The vegetation cover increased first and then decreased with the increase of slope and reached the maximum value when slope was 35 ° to 45 °. For aspect, the overall vegetation coverage of ubac was slightly higher than that of adret. The correlations between different vegetation coverage and different topographic factors were different. The influences of slope and aspect on vegetation coverage of all levels were significantly higher than that of elevation. There was no obvious correlation between elevation and vegetation coverage of all levels.
