Impact Evaluation of Land Consolidation Planning on Environment Based on DPSIR Model
[Objective] Land renovation and the subsequent environmental impact were assessed in 20 land consolidation plans in Qingyang City of Gansu Province to provide a reference for environmental impact assessment by land consolidation in the mountainous area of eht Loess Plateau.[Methods] Based on the DPSIR(driving-force-pressure-state-impact-response) model
a scientific and reasonable evaluation index system was established to assess the environmental impacts of land consolidation in Qingyang City. [Results] (1) The per capita GDP and the increment of arable land had strong driving effect on land change. Impact on ecological environment was prominent by land pollution. City's forest coverage had an important effect on variation of land resources. People's feeling to environment was important with regard to land management
and the interlinks among population
resources and environment
as well. The impact of comprehensive utilization of solid waste was mostly important. (2) The maximum comprehensive environmental impact of land consolidation was assessed at 0.256 9 in Zhoujia village
Shancha Town
Zhenyuan County
and the minimum one was assessed at 0.130 4 in Miaoshan mountain
Taibailiang Town
Qingcheng County. [Conclusion] The comprehensive indexes of all the 20 consolidation areas largely varied between 0.150 0 to 0.250
indicating that the ecological environment in Qingyang City has great improvement potentiality.
