- Abstract:
-
Land ecological security is an important part of the study of the ecological safety issues. It has become the leading issue of the sustainable use of land resources. The security of farmland ecology was analyzed on the basis of analyzing the energy value of the input-output by using the method of energy analysis. The results show that: (1) farmland ecological security situation gradually deteriorated during the study period in Guizhou Province, farmland ecological security situation was in light warning condition in 2000, in moderate warning condition in 2010, which showed that the ecological and environmental problems of farmland became more prominent in Guizhou Province; (2) the degrees of space were obvious differences, showing that the east was lower than west in terms of the spatial pattern, which was related to difference between the east and west in the natural conditions and usage of fertilizer and pesticide.
