土地利用及生态环境效应是全球环境变化研究的重要组成部分。以深圳市福田红树林国家级自然保护区及其周边地区为例,基于多源遥感影像进行土地利用变化分析,进而评估边缘区的生态敏感性,然后采用数学模拟的方法研究边缘区对交通噪声衰减效应的影响。结果表明:研究区在1983—2010年间土地利用变化以基围鱼塘向建设和交通用地转化为主,交通用地给保护区带来严重的噪声污染;声屏障和陆地绿地建成后,保护区噪声影响的鸟类生存适宜区23.86%增加到54.32%,降噪效应非常明显。
Land use and eco-environmental effects are important components of global environmental change research. Taking the Futian Mangrove National Nature Reserve and its surrounding areas in Shenzhen as an example, this paper analyzes the change of land use based on multi-source remote sensing images to evaluate the ecological sensitivity of the marginal zone, and then uses the mathematical simulation method to study the influence of the marginal zone on the traffic noise Effect of decay effect. The results showed that the land use change in the study area changed from the construction of the fish pond to the construction and traffic land in 1983 to 2010, and the traffic land brought serious noise pollution to the reserve. After the sound barrier and the land green land were completed, the noise Affected bird survival area 23.86% to 54.32%, the noise reduction effect is very obvious.
