生态系统评估模型参数空间分布研究

Spatial distribution of ecosystem assessment model parameters

生态系统评估模型参数的获取和空间分布研究是开展生态状况调查评估的重要内容,是对不同区域、不同类型生态系统开展科学评估的必然要求,也是服务各级生态环境保护与管理部门的现实需要。通过系统梳理了目前国家和区域尺度主流的生态系统评估模型和参数,特别是对这些参数的空间分布特征、获取难易程度以及模型可操作性进行了分析。在此基础上,针对不同类型评估参数的空间化存在的问题,从算法、共享、计算、模型适宜性和数据空间连续性5个角度做了分析和总结,并对评估参数空间化的发展趋势做出展望。

The acquisition of parameters and spatial distribution of ecosystem assessment model is an important part of ecological status investigation and assessment.It is an inevitable requirement for scientific assessment of different regions and different types of ecosystems,and it is also a practical need for serving ecological environment protection and management departments at all levels.This paper systematically reviews the current mainstream ecosystem assessment models and parameters at national and regional scales,especially the spatial distribution characteristics of these parameters,the difficulty of obtaining them and the operability of the models.Based on this,the problems of different types of evaluation parameters spatialization are analyzed and summarized from four perspectives:algorithm,sharing,calculation,model suitability and data spatial cnotinuty,and the development trend of spatialization of evaluation parameters is prospected.
