- Abstract:
-
It is important reference value to control the characteristics of arable land fertility and spatial distribution pattern accurately for improving the production capacity of arable land. Heilongjiang reclamation area’s Qianshao Farm was selected as the study area, the plots of land was put as evaluation units, and the quantitative valuation procedure was realized by adopting analytical hierarchical process, fuzzy math, integrating indexes and by the support of GIS techniques. Then we further analyzed the overall characteristics of arable land fertility and spatial distribution of geographical and administrative area. The results showed that farmland fertility was divided into six levels, at the same time, the soil fertility both presented normal distribution characteristics with the third-class and the fourth-class for the peak, and gradually reduced to the fifth-class, the second-class, the sixth-class and the first-class; the fertility of the most arable land was in the middle or upper levels, and paddy field fertility level was slightly higher than that of dry land fertility level because the paddy soil was in high quality and rich in nutrients as well as with proper management; the first, the second and the ninth precincts are in the southwest of Qianshao Farm were the farm’s high quality arable land concentrates.
