苏北低山丘陵区典型森林生态脆弱性评价

Assessment of Ecological Vulnerability of Typicality Forest of Low Mountains and Hills in Northern Jiangsu Province

生态脆弱性评价是当前全球变化与可持续发展研究中的热点问题。以苏北低山丘陵区典型性森林植被为研究对象,通过层次分析法构建了适合苏北低山丘陵区典型性森林生态脆弱性评价指标体系,制定了生态脆弱性评价标准,并根据生态脆弱度将森林植被划分成5个不同的脆弱级别;最后通过加权综合法对该地区典型性森林群落生态脆弱性进行评价。结果表明:该地区典型性森林生态脆弱度排序为侧柏(75.92)>麻栎(54.95)>栓皮栎(53.61)>黑松(49.63)>刺槐(47.68)>黄连木(45.69)>黄檀(44.92)>赤松(43.34)。

Assessment of ecological vulnerability is a hot issue in the research field of global change and sustainable development.North Jiangsu Province area of low mountains and hills in typical forest vegetation was selected as the study site.Assessment index system was set up for typical forest ecosystem vulnerability of north Jiangsu Province of low mountains and hills by means of AHP,ecological vulnerability evaluation standard was developed,and according to the ecological fragile,the forest was divided into 5 different vulnerability levels.Finally,the ecological frangibility of typical forest communities was evaluated by the weighted comprehensive law.The results showed that typical forest ecological vulnerability of low mountain and hill area was in the sequence of Orientalis community（75.92）Sawtooth Oak（54.95）Quercus variabilis（53.61）Black pine（49.63）Robinia（47.68）Pistacia（45.69）Dalbergia（44.92）Red pine（43.34）.
