Abstract

Analysis of the dynamics of modern desertification of the Northwestern Caspian with the use of geoinformation technologies and aerospace data showed that the area of degraded and desertified lands in the region increases due to an increase in the anthropogenic factor (pasture load). With a relatively stable number of animals, the role of climatic factors increases, which leads to an increase in the speed and amplitude of changes in the area of desertification foci, both in the direction of a decrease with sufficient moisture and an increase in dry years. A significant influence is exerted by fires, which lead not only to a decrease in projective cover but also to a depletion of the species composition of vegetation. The study and mapping of the relief made it possible to establish spatially defined geomorphological features of the territory as a factor affecting local moisture and, accordingly, the stability of ecosystems and the possibility of phytomelioration.

西北里海荒漠化的地理信息分析

摘要

利用地理信息技术和航空航天数据分析了西北里海的现代荒漠化动态，结果表明该地区退化和荒漠化的土地面积由于人为因素（草场负荷）的增加而增加。在动物数量相对稳定的情况下，气候因素的作用增加，这导致沙漠化疫源地面积变化的速度和幅度增加，既有充足水分减少的方向，也有干旱年份增加的方向。 。火灾产生了重大影响，不仅导致射影覆盖率降低，而且导致植被物种组成的枯竭。
