The development of the regional forestry industry was uneven.(2)The geographical distribution of China's forest industry and Forest resources was uneven during 1998-2007.The degree of the uneven geographical distribution of the primary industry of China's forestry industry and forest resources was de

我国林业第一产业与森林资源在地理分布上的不均衡程度逐年降低；而我国林业产业总产值、第二产业与第三产业与森林资源在地理分布上的不均衡程度则先在1998-2003年间逐年升高，然后再缓慢下降；(3)1998-2007年间，全国只有浙江、福建、西藏、吉林、黑龙江的林业产业结构对其林业产业增长的贡献始终高于全国平均水平，其他省份的林业产业结构还需调整。

Common types include the distribution of uniform distribution, distribution, distribution of 30 cents, and the distribution of beta log-normal distribution.

Actually, such a generalized Cauchy distribution was the Pearson VII probability distribution. In this dissertation, the Lorentz distribution was regarded as a generalized Cauchy distribution with only one scale parameter; while the Pearson VII distribution was regarded as a generalized Cauchy distribution with a scale and a shape parameter both.

因此，本文提出应在Lorentz分布的密度函数中再增加一个能够反映分布函数尾部特征的形状参数，希望通过该参数的可调节性进一步改善稀疏编码算法的自适应性。

Spatial distribution pattern of larvae of Aleurocanthus spiniferus in citus garden was studied by means of some distribution parameters such as mean crowding, David and Moor's clustering index, index of patchiness, proliferation index, the distribution of negative binomial, Iwao's patchiness, the and Taylor's law. The results showed that the spatial distribution pattern of larvae under all densities appeared to be aggregation distribution, which is characterized by individual attraction and predominant individual group such as cored distribution pattern.
