森林资源调查监测数据的确定性和时效性探讨

Discussion on Certainty and Timeliness of Forest Inventory and Monitoring Data

森林资源年度调查监测近年来一直备受关注。从森林资源调查监测数据的确定性和时效性分析入手,提出应从不同确定性的数据赋予不同权重、提高数据时效性需要优先考虑确定性、提高数据时效性还需兼顾衔接可比性等3方面统筹数据的确定性和时效性。最后,为进一步完善目前的林草湿调查监测工作,提出3点建议:(1)要形成全国一盘棋、国家地方一体化监测的统一认识;(2)要明确兼顾衔接性、统筹确定性与时效性的基本思路;(3)要深化图斑监测技术要求、图斑监测与样地调查联合出数的具体方法。

Annual forest inventory and monitoring has been a concern in recent years.Starting from analysis of certainty and timeliness of forest inventory and monitoring data,it was presented to coordinate certainty and timeliness of data from the following three aspects:(i) data with different certainties should be given different weights;(ii) certainty should be given priority to improve data timeliness;(iii) coherence and comparability are necessary to be taken into account for improving data timeliness.Finally,to further improve current forest resources,grassland and wetland inventory and monitoring,the following three suggestions were put forward:(1)to form a unified understanding of bearing in mind the whole country,and national and local integrated monitoring;(2)to clarify the basic ideas of taking coherence into consideration and balancing certainty and timeliness;(3)to deepen the technical requirements of pattern spot monitoring and specific methods of joint estimation of patern spot monitoring and plot inventory.
