- Abstract:
- Soil erosion problem in Wuhua River Basin was concerned from the perspective of landscape pattern. Based on the temperature, rainfall, runoff, and sediment data in 1981 to 2011 and Landsat TM remote sensing images (1991, 2000, 2011), and landscape patterns (landscape-level and class-level), landscape pattern index analysis and statistical methods were used to analyze the effects of landscape patterns on runoff and sediment. The results showed that:at landscape level, landscape diversity index (SEI), and landscape edge density (ED) were positively associated with runoff and sediment, while landscape shape indexes (PSCV, AWMSI, AWMPFD) were negatively associated with runoff, sediment load, and sediment variation coefficient; at class level, the edge density (PD) and fragmentation (ED) of woodland, the shape index and edge density of grassland, and construction land fragmentation were closely related to runoff and sediment yield, while the patch shape index and area index of woodland, the patch fragmentation of grassland and farmland, the edge density, area and shape index of building land showed a negative relationship with runoff and sediment load; in addition, the shape index of woodland, fragmentation of grassland and arable land, and the edge density, plaque area and shape index of building land had significant positive correlation with sediment variation coefficient.
