This study presents main forest in implements logistic regression model analyze changes area (Jiangxi Province) primary influencing factors for under 1990 2010. Subsequently, (non-traditional landscape pattern index) was built patterns interference modes. The results indicated that total by more than 40,000 ha during period; however, showed large amount high-quality replaced poor-quality because areas present rich soil organic matter (SOM) content are easily converted other types, whereas with poor SOM land. Between 2010, improved proportion interior forests proportions patch perforated decreased. paper concludes proposing some policy recommendations conservation
