| 摘 要： | 基于3S技术、中尺度模式及动态植被模式建立了生态-气候监测预警系统,其中包括4个子系统:土地覆盖动态监测系统、城市热岛动态监测系统、城市气候监测系统和植被NPP模拟与监测系统.利用土地覆盖监测系统可以精确地获取各种土地覆盖类型,并分析土地利用覆盖变化;利用土地覆盖监测系统结果、Landsat-TM红外影像及常规气象资料构建城市热岛监测系统,分析该地区城市热岛效应的时空变化:利用土地覆盖分类结果,对改变下垫面进行敏感性试验,模拟城市发展对城市气候的影响,构建城市气候监测系统:利用LPJ模拟杭州湾地区植被NPP及对气候变化的响应,构建植被NPP模拟与监测系统.生态预警系统可以实时监测土地覆盖、城市热岛、城市气候、植被NPP变化.对保护耕地资源、改善生态环境、提高城市人居环境、合理利用气候资源、保持农林业的可持续发展有着重要的指导和现实意义.

| Abstract: | Based on the 3S techniques, a mesoscale model and a dynamic vegetation model, a monitoring and early warning system for ecology and climate in Hangzhou Bay is built, includingdynamic monitoring subsystems for land-cover and urban heat island, a monitoring and predicting subsystem for urban climate and a subsystem for simulation and prediction of vegetation NPP. The dynamic monitoring subsystem for land-cover monitors the types and variations of land-cover. The results, together with the infrared images of L... |
