These above problems, which are very important and valuable in agricultural crops area monitoring, are currently less researched. Hence, in this paper, seven types of common texture and five vegetation indices were respectively added into TM multispectral bands to classify using three different methods, which are Minimum Distance, Maximum Likelihood and Support Vector Machine, and analyze the effect on winter wheat identification accuracy by comparing the classification results. The contexture include Mean, Variance, Homogeneity, Contrast, Dissimilarity, Entropy, Variance, Angular Second Moment and Correlation, and the vegetation indices are RVI, SAVI, RDVI, NDWI and SLAVI.

Across the altitudinal gradient, a total of 12635 individuals belonging to 6 phyla, 15 classes and 33 orders were collected. With increasing altitude, the density of soil fauna decreased, but the group number was less affected. There was a higher co-occurrence of soil faunal communities along the altitudinal gradient, and Nematoda, Acarina, and Collembola were the dominant groups. Below the altitude 370 m, the Shannon-Wiener index, Pielou index, and Margalef abundance index increased with increasing altitude; while above the altitude 370 m, the Shannon-Wiener index and Pielou index decreased but the abundance index increased after an initial slight decrease.
结果表明:土壤动物密度随海拔升高而下降,类群数受海拔影响较小,各海拔群落的共有度较高,优势类群基本均为线虫、蜱螨目和弹尾目;Shannon-Wiener指数、Pielou均匀度指数及Margalef丰富度指数仅在海拔370 m以下随海拔升高而增加,而在海拔370 m以上,Shannon-Wiener指数与Pielou均匀度指数下降,丰富度指数在略有下降后再次上升。

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。

Because of a high groundwater level and a strong erosion action, the coal formed in a low peat swamp is great in gelatification index and in groundwa ter index, which are in a negative correlation to the ratio of clean coal recove ry. While for the high peat swamp, IG and IGW are small, corresponding to a high ratio of clean coal recovery.
低位泥炭沼泽由于潜水位较高,水流对泥炭沼泽表面的改造和冲刷作用较强,形成的煤层具有较高的凝胶化指数和地下水流动指数,并且与精煤产率呈负相关,煤中粘土矿物和黄铁矿难以洗选;高位泥炭沼泽形成的煤层具有较低的凝胶化指数和地下水流动指数,泥炭积累速度较快,其精煤的产率较高。
