摘要:
对提升式草量计结构进行了改进，将原固定式量板变为活动式，可随被测草地坡度变化而改变角度，始终与坡面平行以均匀作用于冠层。结果表明，在黄土丘陵区长芒草、厚穗宾草坡地草场，改进前的草量计不能估测生物量低于100g/m2的草地，此时量板内边与地表接触。当采用活动式量板后，二草地皆获得极显着的生物量/量板高回归估测方程。对于生长高大，具有高额生物量的沙打旺等人工草地，坡度对测定无显着影响，草量计改进的关键在于增大量板面积或增加配重以改善量板测定时的稳定性，提高精度。并还首次给出了用该草量计对天然草地枯死体的估测方程。
Abstract:
The structure of rising plate meter have been improved by adding additional axle which make the plate can turning with the gradient when working on the slope grassland.The result showed that the improved plate meter could be used to estimate the biomass in loess hilly slope grassland, however there were no relations between biomass and height for old mater where the biomass below 100g/m2 in the Stipa bungeana and Aneuroloepidium dasystachys dasystachys grassland; For the pasture with high plant biomass and canopy the slope had no great effect on meter, the improvement for plate meter is to increase the area and weight of plate to improve the stability of plate when falling on the canopy.The estimate equation for the dead matter of the grassland was also presented in this paper.
