- Abstract:
-
Based on the connotation and factors influencing cultivated land ecological security, evaluation index system was constructed from three aspects including nature, economy, and society by selecting 17 indices which have close relation with land ecological security. The combination weighting method was used to determine the weights of the indicators, and though the quantitative calculation, the paper got the comprehensive value of each county’s cultivated land ecological security in Harbin City. The non-equidistant method was used to divide the comprehensive value into five parts such as safety, relative safety, sensitive, risk and deterioration. The results showed that the cultivated land ecological security was at the relative safety level in Yilan County and Tonghe County; and it was at risk level in Shuangcheng City and Bin County; and the cultivated land ecological security was at sensitive level in the other six county-scale regions.
