- Abstract:
- Evaluation on cultivated land ecological security of a certain area and identifying factors that affecting the cultivated land ecological security can be helpful to guide the rational and sustainable use of land resources. This paper takes the typical mollisols region that is an important commodity grain production base in China- Suihua City on Songnen High Plain in Heilongjiang Province as the study region, evaluation index system of cultivated land ecological security based on ‘P-S-R’ model was established, evaluation on cultivated land ecological security from 2001 to 2009 was performed by using the multiple factors analysis method, and the principal component analysis method was carried to find out the driving forces on cultivated land ecological security by using SPSS software. The results showed that the grade of security cultivated land ecological security was at the poor ecological level in 2001; the grade of cultivated land ecological security had risen to risk level from 2002 to 2004; from 2005 to 2009, the grade of cultivated land ecological security was at a sensitive stage. Natural disasters, serious soil erosion and the contradiction between people and land resources resulted in the ecological security problems in Suihua City. The paper showed that the socio-economic pressures, agricultural science and technology and environmental were the three factors affecting the cultivated land ecological security.
