摘要
建立符合实际情况的植被净第一性生产力模型 ,可以为研究土地承载力和制定人口、环境、资源协调发展战略和规划提供科学依据。详述了植被净第一性生产力模型的国内外研究进展 ,并对现有的自然植被和作物生产力模型进行了简要评价 ,比较其优劣 ,指出了今后的发展方向 :建立植被叶面积指数与生物生产力区域遥感动态模型 ;在全球变化背景下 ,研究生物生产力的变化趋势尤为重要 ;对于作物生长模型应组建模型运行所需的各类数据库。
It's of great significance to construct vegetation NPP model according to actual condition, which can offer scientific evidence for exploiting and protecting natural resources, research on land capacity and the strategy of developing population, resources, environment harmoniously. The paper stated the domestic and overseas progress of vegetation NPP, and briefly evaluated the existing productivity model of natural vegetation and crop. The paper also put forward the direction of research in future: to construct district RS dynamic model between LAI and productivity, to research the changing trend based on global change, to set up all kinds of database for crop growth simulation model.
