摘要
珠江源自然保护区地处滇东高原 ,总面积 2 30 4 5 9 0hm2 ,森林覆盖率 5 7 5 %。其特点是树种组成单一 ,中幼林多 ;农林交错、次生林占优势、林分质量差 ;森林生态脆弱。对本自然保护区的森林生态功能评价 :①总体生态功能“差” ;②森林生态脆弱 ;③蓄水、保土、保肥、增产等效益显著 ;④具有生物多样性特点。对今后森林资源的保护、发展提出了建议。
Zhujiangyuan nature reserve located in the plateau of eastern Yunnan, with the total area of 230 459 hm2 and the forest cover percentage of 57.5%. The vegetation characteristics of Zhujiangyuan nature reserve was simplified species composition, major in half mature and young forests, dominant with secondary forests, low stand quality, and sensitive ecological system. The overall evaluation were low ecological function; sensitive ecological system; significant functions of conserving water, soil, fertilities and increasing agricultural yield; conserving biodiversity.
