The soil physical properties and chemistry characteristic had been studied during controlling of karst rocky desertification process in the karst rocky mountainous areas. The result showed that: in controlling rocky desertification process

the numbers of individuals and density of plant increased with the degree of soil meliorated. Soil compaction decreased

and soil porosity

capacity of water and fertility holding increased

soil organic matter increased

these were associated with the soil organic matter contents and plant coverage

the total numbers of bacteria

antinomycetes and fungi increased. Bacteria was dominate group

the numbers was increased: soil bacteria> fungi > actinomycetes. Meanwhile soil fertility and productivity increased.
