Abstract

Optimizing and improving National Continuous Forest Inventory System is an important concern in recent years.According to the distribution characteristics of forest resources in Tianjin and previous Continuous Forest Inventories (CFI) results,the sampling design of CFI in Tianjin was optimized and improved,and the optimal sampling design was verified and analyzed using the implementation results in 2017.The results showed that one 500m sample line was similar to three 0.066 7 hm2 (1 Chinese mu) sample plots on sampling efficiency for estimation of forest area,the sampling precisions of forest area and growing stock volume were more than 90% as specified in national technical regulation,and those of forest area and forest volume in two sub-populations,i.e.,mountainous and plain areas,were more than 85% and 80% respectively.Finally,it is concluded that sample line based survey is an effective way to conduct CFI in plain area,stratified sampling is a highly effective method to improve the efficiency of CFI,and the optimization and improvement on sampling design of CFI in Tianjin have met the precision demands and achieved the expected results.

Key words： forest resources; continuous inventory; stratified sampling; optimization; improvement
