摘要
本文叙述利用多级遥感技术进行森林立地分类与质量评价。首先采用卫星磁带数据进行图象处理,在图象判读的基础上,提供了旺苍县的立地分区。进而利用航空象片进行立地因子的判读,按影响立地的因子划分立地类型和评价立地质量。由于立地研究是以遥感图象为载体,所以在研究中立地分类与立地制图相结合。本文的最后部分还讨论了立地分类与评价在防护林工程中的应用。试验表明,本方法与常规技术相比,不仅具有速度快,效率高和成本低的特点,而且立地信息丰富,便于生产中应用。
In this paper the authors have studied the use of image information of multistage re- mote sensing for the forest site classification and site quality evaluation in Wangcang County of Sichuan Province(East river basin of Garling branch of yangtze river). There are a few sepecific procedures as follows: 1.Using the LANDSAT digital image to interpret macroscopical forest site units. 2.Using the aerial photographs to interpret detailed forest site units. 3.Using the site factors to evaluating forest site quality. 4.Site mapping. In this experiment,the result of investigating the forest site in Wangcang County was divided into 2 site areas,5 site sub-areas,2 site groups,and 27 site types. By check,it is verified that this method is efficient.
