基于DPSR模型的涉及自然保护区海岸带生态安全评估研究
Coastal Ecological Security Evaluation in Nature Reserve Based on the DPSR Model
摘要
Abstract
Taking Dongtai coastal zones as an object of study, an coastal ecological security index system of Dongtai was constructed according to the driving DPSR model and the actual instance of Dongtai. And then the ecological security status in this area was evaluated by the weighted PCA model in the years of 1984, 2001 and 2011 with the support of the technology of CIS and RS by collecting the topographic map and remote sensing image in different stage. The calculation results showed that the total score of ecological security (F) was 3.242, 0.279 and -3.521 in 1984, 2001 and 2011, respectively. The level of ecology security decreased apparently with accelerated downward trend, and would reduce because of deterioration of ecological environment and biodiversity decrease, which is mostly reflected in the state index.关键词
