多源遥感与生态监测支持下的湿地景观稳定性模型的构建及景观优化研究

Landscape stability is an important scientific problem in Landscape Geography and Landscape Ecology, there has been nearly no perfect system to quantify and evaluate it yet.Only few institutes and scientists carried out some researches that focused on landscape stability,especially in China. The aims of our project are to study landscape stability at Zhalong Wetland in China with synergistic analysis of multi-source RS data and ecology monitoring, then we will explore an optimized scheme of wetland landscape adjustment.These works will be conducted with the support of science theories,landscape surveys and spatial observation technology. Firstly, the current project will continue field investigations and monitoring, to define some important landscape parameters to analyze landscape dynamic trend and to find driven mechanism of landscape dynamic; Secondly, we will select suitable based -disturbance index to evaluate landscape stability and further develop an integrated model of landscape stability in wetland landscape; Finally, the project will propose to an optimized scheme to adjust structure and pattern of wetland landscape. The research can provide a classic case for studying landscape stability,and it can also enrich the theory and approach of landscape ecology; In addition, the project will provide a scientific guidance to protect and manage wetland landscape.

景观稳定性是景观地理学和景观生态学的重要科学问题，但却一直没有成熟的科学体系来量化和评价它，尤其在国内研究景观稳定性的并不多。本项目基于景观生态学、数学、计算机等科学方法和理论，在地理信息系统技术支持下，结合多源遥感数据和景观调查监测对黑龙江省扎龙湿地景观稳定性进行研究并以此为数据驱动探求景观优化方案。首先通过景观生态监测及多源遥感定量反演，确定相应的景观参数进行湿地景观的动态趋势研究，探寻景观动态驱动机制，确定景观动态干扰来源；其次通过景观动态干扰源的确定来选取合适的评价指标，建立基于控制-干扰-响应机制的稳定性评价框架和模式；然后以景观动态和干扰两个角度出发，构建景观稳定性综合模型并进行尺度验证；最后进一步提出湿地景观优化及调控方案。本项目可以为景观稳定性研究提供实例示范，完善和充实景观生态学理论和方法体系；对于湿地景观的保护与管理具有重要的指导意义。
