Dynamic Observation Method of Carbon Cycle in Arid Area Based on GIS Technology

土地利用、土地覆盖以及碳循环问题是和当今人类生存发展息息相关的热点问题,为了有效对干旱地区的碳循环进行观测,设计并提出基于GIS技术的干旱地区碳循环动态观测方法。主要通过遥感、GIS技术以及生态模拟方法进行研究,选取较为典型的干旱地区为例,分析干旱地区内的土地利用、土地覆盖变化以及碳循环问题。对干旱地区不同时间段内生态系统的影响进行土地利用、土地覆盖分类;根据对比、分析获取干旱地区内的土地利用、土地覆盖变化情况,通过GIS方法分析干旱地区的植被生长情况,依据生态模型模拟干旱地区碳循环过程,以完成干旱地区碳循环动态观测。仿真实验结果全面验证了所提观测方法的有效性以及实用性。

Land use,land cover and carbon cycle issues are hot issues closely related to human survival and development.In order to effectively observe the carbon cycle in arid regions,a GIS-based method for dynamic observation of carbon cycles in arid regions is designed and proposed.The research is mainly carried out through remote sensing,GIS technology and ecological simulation methods.The typical arid areas are selected as examples to analyze the land use,land cover change and carbon cycle issues in arid areas.Classification of land use and land cover on the impact of ecosystems in different periods in arid regions;Obtaining land use and land cover changes in arid areas based on comparison and analysis,and analyzing vegetation growth in arid areas by GIS;Simulate the carbon cycle process in arid areas based on ecological models to complete the carbon cycle dynamic observation in arid areas.The results of simulation experiments fully verify the effectiveness and practicability of the proposed observation method.
