植树种草可以防风固沙已成为人们的共识。然而 ,中国科学院水生生物研究所的一项藻类学最新研究成果显示 :通常在显微镜下才能观察到的荒漠藻类实际上才是沙漠中的先锋拓殖生物 ,这项成果开辟了综合治理荒漠化的新途径。据分析 ,土壤的生态演替过程往往是组成物种由低等到高等 Planting trees and grass can wind sand fixation has become the consensus. However, a recent study on algae by the Institute of Hydrobiology, Chinese Academy of Sciences, shows that desert algae, which is usually observed under a microscope, is actually the vanguard of desertification. This achievement has opened up a new way for comprehensively combating desertification . According to analysis, the process of soil ecological succession is often composed of species from low to high
