| 摘 要： | 以内蒙古托克托县枸杞灌木作为研究对象,利用照相技术和图像处理软件获取各植株侧面宽度D、植株高度H、侧面照相面积S等参数,建立起基于这些参数或参数组合的枸杞地上生物量拟合方程。经过检验,以植株侧面照相面积S为自变量的幂函数回归模型可用来估算枸杞地上生物量。侧面照相面积S与植株的生长状况密切相关,通过照相技术和图像处理软件获取S等参数相对简便、准确,在实际操作中能提高工作效率。

| Abstract: | Lycium barbarum L. Shrub was taken as research object in Tuoketuo county of Inner Mongolia,some parameters such as plants’ width（ D）,height（ H） and plant side area（ S） etc. were extracted by using photographic technique and image processing software. The different kinds of fitting equations of aboveground biomass were established on the base of those parameters or parameters combination.Power function regression models were applied to estimate aboveground biomass of L. barbarum after testing. Plant side area of photo was closely related to growth situation of plant. Using photographic technique and image processing software could improve work efficiency in practice,and also could obtain parameters more simple and accurate. |
