The goal of this study was to investigate how laser point data could be explored systematically to measure important growth parameters of wheat such as crop height, degree of coverage, and biomass density in crop yield monitoring.

( d) bottomland meadow; In the meadow, montane meadow has higher aboveground biomass density than alpine meadow.

草甸类型中，山地草甸（117.4gC·m-2）的地上生物量密度显著高于高寒草甸（58.1gC·m-2）。

The main conclusions were as followed: ( 1) The ecosystem services of buffer strips were related to plant species, crown density and tridimensional green biomass density.

主要研究结论如下：（1）缓冲带的生态服务与物种、郁闭度和三维绿量密度有关。

Cruentum cells grow very slowly in the natural and artificial seawater medium, and the biomass density is also lower.

紫球藻在海水基础培养基中生长缓慢，培养密度低，这就为从其细胞内提取活性物质增加了成本。

Ash has much higher fine root biomass density in the soil than larch at stand level ( with the max value of 4442.3 vs. 2234.9 gm-3).

在林分水平上，水曲柳的根生物量密度高于落叶松（分别为4442.3和2234.9g/m3）。

Biomass density and plant density had an insignificant influence on herbivores intake rate. While plant size had a significant effect on intake rate.

生物量密度和植物密度对动物摄入率无明显影响，而植物大小对动物摄入率则有显著影响。

Submerged plant is an important makeup in Lake Ecosystem. Species, biomass, mulch area, spatial distribution, fashion and degree used of submerged plant are directly related to the environmental quality of the lake.

沉水植物是湖泊生态系统的重要组成部分，湖泊沉水植物的物种组成、生物量、覆盖面积、空间分布、被利用的方式及程度都直接关系到湖泊环境的整体质量。

The results suggest that in order to estimate the confidence interval of the number of species and biomass, a larger sample size ( e.g. n ≥ 50) is needed.

结果说明，要估计一个变量的置信区间，需要有足够大的样本含量。

At herd the grass growth season, 5 kinds of main dominant species forage biomass is 50% that total forage biomass;
