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

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).
