The results showed that: with the regression analysis of Betula platyphylla, Pinus koraiensis, Abies nephrolepis, Picea koyamai var koraiensis, and Betula costata, there was a significant negative correlation between neighborhood interference index and the growth (0.40~0.89) and the correlation extent depended on the neighborhood influence zone and slope. The neighborhood influence zone corresponding to maximal regression coefficient R~2 was the neighborhood influence radius. Based on the linear subsection regression between neighborhood interference index and influence zone of five species, the neighborhood interference index increased with the increasing zone and there was a previous increasing trend in a certain scope, while the increasing trend slackened beyond the zone. The neighborhood influence zone corresponding to transition point was the neighborhood influence radius. The neighborhood interference index positively correlated with the neighborhood influence zone and the range of R~2 was 0.40-0.64. With the analysis of tree cores of Juglans mandshurica, Fraxinus mandshurica at middle and lower slope in a plot which was fostered in 1995, the distance which the growth release farthest neighborhood and object stub was judged, thus the neighborhood interference radius was inferred. According to the studies, we found that the neighborhood interference radius was different among different trees, even if the neighborhood interference radius of the identical tree species also had the difference at different slopes.

结果表明：通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与生长量回归分析发现，邻体干扰指数与生长量呈显著负相关(0.40～0.89)，相关程度因邻体影响范围和坡位而异，R~2达到最大值所对应的影响范围即为邻体影响半径；通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与影响范围的线性分段拟合，邻体干扰指数随影响范围的增加而增加，其在一定的范围内上升较快，而超出该范围后上升的幅度变慢，变化的转折点所对应的影n向范围可以判定为邻体影响半径，线性回归显著(0.40～0.64)；通过对1995a抚育的胡桃楸、水曲柳样树进行研究，分析邻体树种的中坡位和下坡位的生长锥芯，判断产生生长释放的最远邻木与基株树桩所对应的距离，推断邻体影响半径；根据研究发现，邻体影响半径因树种不同有一定的差异，即使同一树种的邻体影响半径在不同坡位也有一定的差异。

四是通过考察社会转型以来城市邻里空间的变迁，以及国家在期间扮演的角色，发现随着单位制解体，邻里社区开始在城市社会管理中发挥重要社会功能，在"社区建设"的话语下，国家与城市邻里空间的关系从原来的"威权控制"转向"体制吸纳"，国家策略性地为社会创设一定空间，通过其在基层的代理人"居民委员会"的制度运作，始终将生长中的社会力量吸纳入国家体制可控的轨道之中。

The method includes the following steps: firstly, a spherical neighborhood of present sample points is established by using the geometric spherical-modelling theory and all the sample points contained in the spherical neighborhood are adopted as candidate neighbor points, thus not only preserving the effectivity of the dimension reduction capability when data sets are sparse but also getting the advantages of low-sensitivity to isolated points and good stability of the preserved topological structure; then a data relevance matrix more matching semantics can be obtained by relevance measurement based on route clusters to update the candidate neighbor points in the spherical neighborhood and optimize the regular neighborhood space of the present sample points, thus improving the phenomenon that the dimension reduction of sample sets provided with folded curved faces is apt to suffer the integrated-structure distortion in case of heterogeneous data distribution.

首先利用几何开球原理建立当前样本点的球状邻域，将包含在球状邻域内的所有样本点作为候选近邻点，不但能够保持在数据集稀疏情况下的降维性能的有效性，而且具有对孤立点敏感性不高、保留拓扑结构稳定性好的优点。然后利用基于路径聚类的相关性度量得到更符合语义的数据相关性矩阵，用来对球状邻域内的候选近邻点进行更新，优化当前样本点的规则邻域空间，改善了当数据不均匀分布时在带有折叠弯曲面的样本集上降维容易出现整体结构扭曲的现象。
