森林资源调查监测中各级储量数据的一体化方法研究
A Study on Integration of Forest Stock Data at Different Levels in Forest Inventory and Monitoring
开展国家和地方森林资源一体化调查监测,将各省森林储量数据分解落实到市、县、乡各级乃至每一个森林图斑,是推进各级林长制督查考核的必然要求。基于近年北京市森林资源调查监测的数据资料,以全市森林储量为总体控制数,利用蓄积量估测模型及三储量(蓄积量、生物量、碳储量)联立模型,将储量数据落实到图斑;在有森林资源规划设计调查数据可参考的前提下,可统筹考虑不同数据的误差,采用联合估计的方法,对市、县级数据进行适当调整。通过建立北京市的森林蓄积量估测模型和三储量…查看全部>>
It is necessary to conduct national and local integrated forest resources inventory and monitoring,and implement decomposition of provincial forest stock data to prefecture-,county-,and township-level,and even every forest stand polygon,for promoting the supervision and assessment of forest chief system at all levels.Based on the data of forest resources inventory and monitoring in recent years in Beijing,the procedure for implementing decomposition of fores…查看全部>>
