There are two main problems of degraded land: (1) land degradation; (2) land capability being not rationally utilized. This paper develops and applies three theories of landscape ecology in landscape ecological reconstruction in some degraded land. They are: (1) man should cooperate with nature; (2) the biocybernetic symbiosis; (3) the hierarachical organization of nature. Biological production functions must be combined with ecological protection functions in landscape ecological reconstruction of degraded land. They may reconstruct the complex eco-system of forest, grass and farm land of sandy degraded lands, and construct the sand dams in the longdepressed land between sandy dunce, and according to land types of site, plant some wet-suitable plants such as Hibisczzs cannbinzzs, Elezzsine sp. and Phragmires sp. etc.
