摘要:
<正>以西峡县2个年份同一季节的遥感数据为研究对象,利用图形处理软件(ERDASIMAGINE)进行波段组合、图像增强、监督分类、矩阵分析和分类重编码,研究了河南省西峡县森林资源的时空变化。并且在此基础上利用GIS软件进行统计分析和遥感制图,从时空序列上分析了森林资源的动态变化情况。结果表明:从时间序列上看,1998~2002年西峡县阔叶林面积和针叶林面积有所增加,增加部分主要来源于退耕还林和荒地的植树造林;从空间序列上看,森林植被的变化主要集中于低海拔地区,高海拔地区主要集中于道路和河流附近。
Abstract:
Physical properties of pulping properties of Japanese larch(Larix kaempferi) in different ages(12,15 and 23 years) were investigated. As a result, the physical properties of KP unbleached pulp were close to B grade national standard of unbleached softwood KP pulp, those of KP bleached pulp reached A grade national standard of bleached softwood KP pulp. The physical properties(except whiteness) of AS-AQ pulp,including unbleached pulp and bleached pulp, all reached A grade national standard. Moreover, the tensile strength index, breaking length, folding endurance and burst index of AS-AQ pulp were higher than those of KP pulp. However, the tearing index was opposite.
