补充资料:玉溪哀牢山自然保护区
哀牢山自然保护区位于新平县与景东、镇沅、楚雄、双柏等五县交界处。海拔2080—3165.9米。1986年,云南省人民政府明文划定保护区面积是21.99万亩。1988年,经国务院批准为国家级自然保护区。
哀牢山是云岭南延支脉,第四纪喜马拉雅造山运动期间,由于地面抬升,河流下切,高差增大,而形成今天深度切割的山地地貌。由县酒江自西北向东南斜贯直下,江西部哀牢山脉与里洒江为平行走向,山川交错,山高谷深。哀牢山主峰大底岩海拔31659米,耸立在者是乡与镇流县接壤处。次峰大雪锅山海拔刀刃米,云缠雾绕,巍峨壮观,植物分布区系复杂,古老名贵植物种类较多,在气候、地质生物等方面有较高的科研价值,是自然保护区的核心区;中外科学家合作考察研究的重要基地之一。著名的大帽耳山、小帽耳山,蟀嫔玉立、千姿百态。江边一带多冲积扇和山匠,是发展粮食和热带经济作物的理想之地。江东为云南高原南部边缘地区,多属中山中切割地貌,适宜云南松和中亚热带水果生长。
