In order to know about the stands state of five shrub forest transformation models and give somemanagement advices on Xiaolongshan in Gansu, the paper used spatial structure parameters of the angle index,mingling, neighborhood comparison and species diversity indictor to study the stand composition, structure featuresand species diversity, the result showed that the zonal cutting shrub p lanting Pinus a rm and iimodelwas better thanothermodels in composition, stand structure, species diversity and the stands were easier to become uneven-agedmixed forest, while the zonal cutting shrub p lanting was benefit in imp roving species diversity, mingling anddistributing in random pattern than overall cutting shrub p lanting. In future is management, some measurementscould be adevp ted to op timize the structure and space allocation, so as to p romote the p rogress of stands successionand achieve naturalization.
