A STUDY FOR THE EXPLOITATION AND UTILIZATION OF UNUSED HILLSIDES AND WASTE LAND IN LIUJIANG COUNTY, GUANGXI

Many types of uncultiveated land resources cover large area and spread widely and continously in Liujiang County of Guangxi Zhuang Autonomous Region. But most of them have steep slope and the soil is thin and poor fertilized. The red soil of the Quaternary period and the calxareous soil are the main soil types. Because Liujiang County lies in the warm subtropical zone, it is rich in sunshine,heat resources and species. The favorable location helps itsexploitation and utilization to the uncultivated land resources. In order to decide the pattern of utilization,the suitability of the uncultivated land was appraised in view of the agriculture and the outcome suggested that developing forestry and orchard should be the focal point and developing animal husbandry reasonablely together. While exploring, it should obey sustainable developing principle and keep in line with local conditions. The easier one should be explored first, then promote it in all areas by drawing upon experience gained at key points. The resources should be developed on 3 principles. In the end, the ways for developing were drawn out: to coordinate the man-land relationship to put into more capital to reform the landuse institution to definite the ownership clearly and to work out the mid-long term plans of development. Based on the analysis of land characters,exploiting conditions and land suitability eluvation of unused hillsides and waste land in Liuijang County,the rules and ways of land exploitation have been discussed.
