辽宁沿海城市带生态风险综合评价
Integrative assessment of ecological risk in coastal cities of Liaoning Province, Northeast China
摘要
Abstract
Based on the remote sensing images of 1992 and 2007, and by using GIS spatial analysis technique, a model about the land use change and population increase pressure in the coastal cities of Liaoning was built to comprehensively assess the ecological risk of these cities. The results showed that in 1992-2007, the ecological risk presented a pattern of gradual increasing from inland to coastal area, i. e. , from north to south, with higher risk in flat, traffic-developed, and densely populated areas but lower risk in high elevation and less human disturbance mountainous and hilly regions. The transfer matrix of the ecological risk indicated that in the 15 years from 1992 to 2007, the conversion between different ecological risk levels was mainly from low-grade to high-grade risk, the ecological pressure of the cities became increasingly larger, and both the level and the scope of the ecological risk were increasing.关键词
