遥感探测和绘制生物土壤结壳分布图的能力提供了机会，可将针对具体地点的结壳生态研究扩大到区域范围，从而减少与地面调查有关的时间和费用。然而，尽管土壤结皮遍布全球，人们对其生态作用的兴趣也在不断扩大，但发表的关于利用遥感探测和绘制其分布图的研究报告相对较少。（Wessel和货车Vuuren（1986年））是第一个利用卫星图像探测和绘制生物土壤结壳图的人。他们对非洲西南部纳米布沙漠的研究使用了陆地卫星TM来区分苔藓覆盖的地区和裸露的地面以及植被覆盖的表面。随后，只有相对较少的出版物介绍了生物土壤结皮的光谱特性或应用遥感技术对其进行测绘（Clark等，1993 a，B，c; Kokaly等，1994;奥尼尔，1994; Karnieli和Tsoir，1995; Karnieli和Sarafis，1996; Karnieli等，1996，1999; Tsoir和Karnieli，1996; Tromp and Steenis 1996; Karnieli 1997）。
The ability of remote sensing to detect and map the distribution of biological soil crusts offers the opportunity to extend site-specific ecological studies of crusts to a regional scale, thus reducing the time and costs associated with ground surveys. However, despite the global extent of soil crusts and the expanding interest in their ecological roles, there have been relatively few studies published on the use of remote sensing to detect and map their distributions. (Wessels and Van Vuuren (1986)) were the first to use satellite imagery to detect and map biological soil crusts. Their study of the Namib Desert of SW Africa used Landsat TM to discriminate lichen-covered areas from bare ground and vegetated surfaces. Subsequently, only a relatively small number of publications have either presented the spectral properties of biological soil crusts or applied remote sensing to map them (Clark et al. 1993a, b, c; Kokaly et al. 1994; O’Neill 1994; Karnieli and Tsoar 1995; Karnieli and Sarafis 1996; Karnieli et al. 1996, 1999; Tsoar and Karnieli 1996; Tromp and Steenis 1996; Karnieli 1997).
