- Abstract:
- According to the basic farmland demarcation with the requirement of quality and quantity, 291 farm of red booming land reclamation area was taken as an example, index system of identifying the general farmland as the basic farmland was established based on three level factors of the cultivated land natural quality conditions, location, and cultivated land surrounding, and retrieved space attribute data of individual evaluation index with the aid of GIS technology. By using interval assignment method for cultivated land quality and sort of advantage and disadvantage location, a basic farmland demarcation method of cultivated land quality evaluation based on the foundation responsible for the quantity was set up. The results showed that the proportion of high quality land in 291 farm was low, and distribution was more dispersed. If the basic farmland protection ratio meets the state index, cultivated land area scored 70 points or more was the ideal basic farmland protection area. The empirical research showed that this method can reduce human interference for the basic farmland demarcation, and make the designation of the basic farmland more scientific and reasonable.
