通过建立纵向岭谷区生态环境对气候变化的适应性评价指标体系,构建纵向岭谷区生态环境对气候变化适应性的综合评价模型,并根据评价结果对纵向岭谷区生态环境适应性的空间分布特点做出分析。研究表明:纵向岭谷区生态环境对气候变化适应性的总体状况一般,生态环境适应性好和较好的类型区面积仅占了纵向岭谷区总面积的40.37%,主要分布在南部海拔相对较低、自然地理环境条件优越,以及人类活动向有利于生态恢复方向发展的地区;适应性较差和差的类型区面积占了全区总面积的59.63%,主要分布在北部高寒山区,植被破坏严重、相对贫困的地区。因此对该地区应加大生态环境建设力度,防止生态环境的进一步退化,提高对气候变化以及其他外界干扰的适应性。
The mountainous ecosystem in the Longitudinal Range-Gorge Region (LRGR) is a complicated spatial composition of life system and environment system under the peculiar ecological and geographical backgrounds. Active geotectonic result in topographic unconformity, the rich and diverse ecosystems formed and influenced by unique environmental patterns in this region have attracted the strong interest of geologists and ecologists. By making an assessment index system, this paper builds the assessing model of eco-environmental adaptability of LRGR based on the analysis of result data. The study results show that the eco-environmental adaptation of LRGR is not very good. The ability of adaptation to climatic change in the study area is far from the developed cities in the Yunnan province while the ability of adaptation in the lowland is larger than that in the plateau. The good adaptation area that is only 40. 37% of the total area of LRGR is distributed in the region with advantaged natural conditions and remarkable ecological recovery, southwest part of the LRGR. While the weak adaptation area that is 59. 63% of the total area of LRGR is located in the north part of the LRGR, high and cold mountains. The government should pay more attention on the eco-environmental construction work, and protect the eco-environment from farther degenerating in this area.
