飞来寺国家森林公园景观开发强度动态研究

Dynamic Study on Landscape Development Intensity of Feilai Temple National Forest Park

基于遥感及GIS监测技术,研究了飞来寺国家森林公园近16年内的景观结构及环境健康动态变化特征。结果表明:森林公园景观类型以林地景观为主,面积占比达95%左右;建设用地面积随时间变化而增大,2004—2011年间增速较快,2011年后增速减慢;林地景观面积则随时间变化而减小,减速较快的时期处于2004—2011年间,2011年后速率明显降低;森林公园的景观斑块数量逐年增加,景观破碎度逐年增大;干扰区域主要集中分布于森林公园的东北角;森林公园的景观开发强度综合指数随时间的变化而逐渐增大,但增幅较小,整体上森林公园的环境健康等级处于“健康”水平。

Based on remote sensing and GIS monitoring technology,the dynamic changes of landscape structure and environmental health of Feilai temple National Forest Park in recent 16 years were studied.The results showed that forest landscape was the main landscape type of forest park,accounting for about 95%of the total area;the construction land area increased with time,increased rapidly from 2004 to 2011,and slowed down after 2011;the forest landscape area decreased with time,and the rapid deceleration period was in 2004 to 2011,the less rate decreased significantly after 2011;the number of landscape patches increase year by year,and the landscape fragmentation increase year by year;the disturbance areas were mainly distributed in the northeast corner of the forest park;the comprehensive index of landscape development intensity of forest park gradually increased with the change of time,but the increase was small,and the environmental health level of forest park was“healthy”Level.
