Measurement of soil respiration rate in different stage and different microhabitat of identical stage was carried out in degeneration vegetation recovery procedure in Huajiang typical karst district of southwest in Guizhou province.

Seven microhabitats of stony surface,stony gully,stony crevice,stony cave,stony dais,stony pit and soil surface were divided according to the development current situation of complex and diverse habitats in Maolan Karst region.

What s more,enzyme activity of sucrase,urease,amylase,catalase,phosphatase and polyphenoloxidase were determined in three microhabitats relating t.

A niche entropy-based adaptive hybrid genetic algorithm is proposed,which introduces entropy into the niching method of sharing scheme.
