摘要: 通过结合植被生态遥感和野外调查对苍山植被覆被类型及其变化开展调查研究。植被遥感解析发现,苍山植被垂直带谱分布格局明显,亚高山带植被群落类型及其转移变化较复杂,核心保护对象苍山冷杉林主要分布于东坡高山带。随着保护区的建立,苍山植被覆盖度得到了显著提升,各功能分区已基本完全恢复为高覆盖度植被。野外群落调查发现,苍山冷杉林和多变石栎林群落结构稳定,一些海拔区段华山松林、云南松林和旱冬瓜林群落存在衰退风险。相较于以往单一方式的科学调查,本次遥感影像有效地促进了苍山植被覆被类型及其分流变化的解析,能够与野外调查结果相互支持,而对多种植被群落亚型、群系和群丛的野外调查验证依然非常必要。

Abstract: The vegetation cover types and their distribute changes in Cangshan mountain were studied by combining vegetation ecological remote sensing and field investigations. Based remote sensing analysis of vegetation, the results showed the vertical vegetation spectrum distribution pattern was obvious in Cangshan mountain, and the community types and their interconversion in the
subalpine vegetation zone were complicated. The Abies delavayi forest, as the core protected object, was mainly distributed in the alpine zone of eastern slope. With the establishment of protected area, the fractional of vegetation coverage of Cangshan mountain increased significantly, and all functional zones had been fully restored to high coverage vegetation. Through the field vegetation community investigation, the community structure of Abies delavayi forest and Lithocarpus variolosus forest was stable, and at some elevations, the communities of Pinus yunnanensis forest, Pinus armandi forest and Alnus nepalensis forest were at risk of decline. Compared to the previous single method of scientific investigation, this remote sensing image could effectively improve the deciphering of vegetation cover types and their interconversions in Cangshan mountain. At the same time, the results from remote sensing analysis and field investigation can support each other well. However, it is still necessary to conduct field investigations and verifications of subformation, alliance and association of various vegetation communities.

Key words: vegetation type, vertical vegetation spectrum, vegetation cover changes, community structure and succession
