From 2006 to 2009, with the enclosure of fenced-off farmland for returning cultivated land to forests in Liupanshan, Lund County, Ningxia as the research object, Chinese herbal medicines with organic combination of banning, fencing, artificial replanting and artificial tending were carried out Artificial replanting technology research; and cover fencing area and the control area of the main Chinese herbal medicines coverage, density, frequency, height and aboveground biomass and plant species diversity were investigated and studied. The results showed that artificial replanting of Chinese herbal medicines in the conversion of cropland to forestland under fenced enclosure can effectively increase the vegetation coverage, protect biodiversity and promote the restoration of ecological environment, and has significant economic, ecological and social benefits, and has a high popularization and application value.
