- 摘要:
- 以左江流域作为研究区，选取景观破碎度、景观分维数和景观分离度3个景观格局指数，以及土壤侵蚀敏感性、石漠化敏感性2个生态敏感性指数构建景观类型干扰度和区域生态脆弱度模型。利用空间采样和地统计学插值，生成生态脆弱度空间分布图，实现对流域的生态脆弱进行综合定量的分析和评价。结果表明：（1）变异函数分析表明，流域生态脆弱度的块金值/基台值达65.34%，呈明显的空间相关性，生态脆弱度的空间变异在16km以内比较接近，具有明显的各向同性的特点，而16km以外则表现出明显的各向异性；（2）区域生态脆弱度的空间格局与流域实际吻合良好，呈现南低北高的格局，脆弱程度相对较高的区域与碳酸盐岩在研究区的分布较为一致，地质地貌是流域生态脆弱度空间格局的主要控制因素，而人类活动的影响是引起生态环境脆弱度空间异质性的主要因素。
- Abstract:
- The ecological vulnerability of Zuojiang river basin was assessed using a combined landscape pattern and ecological sensitivity approach.The landscape indices and ecological sensitivity indices are developed by using the landscape isolation,fractal dimension,fragmentation,sensitivity of soil erosion,and sensitivity of karst rock.The network covering the whole study area is used to sample and geostatistics interpolate the spatial vulnerability of ecology,thus,the map of vulnerability distribution of the ecological vulnerability is derived,and the ecological vulnerability is analyzed and assessed.The results showed that:(1) The semi-variogram analysis showed that the regional ecological vulnerability had a relatively good spatial correlation in the study area,the ratio of Nugget and Partial Still is 65.34%.The spatial variability of the region was in an obvious isotropy within 16 km,but existed distinct anisotropy character outside 16 km;(2) There is a good agreement between the predicted and actual distribution of regional ecological vulnerability.The regional vulnerability index was higher in south area than that in north,the higher degree of vulnerability matches with the distribution of carbonate.Geology and geomorphology are the dominant factors affecting the spatial pattern of the regional ecological vulnerability,and human activities are the major factors inducing spatial heterogeneity of ecological vulnerability.
