草原可燃物动态研究

Dynamics of Combustible Matterials on Grassland.

该项研究包括两个部分 ,即定位监测研究和路线抽样调查。定位监测研究是在容易发生草原火的典型草原区和草甸草原区以及黄土高原区选择具有代表性的典型地段 ,每年进行四次定位监测 ,取得草原可燃物量及其含水量以及土壤含水量在时间上的变化 ;路线抽样调查是在进入草原防火期 (9月 15日以后 ) ,草原可燃物量亦达到峰值期或翌年 4月下旬草原可燃物量处于最低值时分别进行路线抽样实测 ,取得草原可燃物量及其含水量在空间的变化。通过进一步研究草原可燃物量及其含水量在时空的动态变化规律 。

This project included two parts,i.e.,mornitoring study in fixed site and sampling investigation along route.The mornitoring study is that the mornitoring is done for four times in typical site of steppe,meadow steppe and loess plateau in which the fire takes place easily to obtain the changes of the amount of combustible matterials and water content in combustible matterials and soil moisture with time;the sampling investigation along route is that real sampling measure along route is done to obtain the changes of the amount of combustible matterial and its water content in space from September 15 to late April next year.The further study on dynamic changes of the amount of combustible matterials and its water content in space and time may provide scientific basis for fire prevention on grassland.
