干旱半干旱区土地整理的生态安全性问题探讨--以新疆为例

土地整理的实施在很大程度上既能有效增加耕地面积,缓解人地矛盾,实现经济效益上的最大化,又能兼顾社会和生态效益,带来社会福利的最大化.然而,对于干旱半干旱地区来说,现实土地整理活动却由于未能充分考虑干旱半干旱地区特殊的自然地理气候状况而存在整理的成本外溢现象,即外部负效应,从而未能达到帕累托最优.应用福利经济学相关理论从理论和实践两方面对土地整理的负外部效应进行分析,并提出相应的对策建议.

An Analysis of Ecological Safety in Land Consolidation in Drought and Semi-drought Areas --A Case Study of Xinjiang

Land consolidation can not only provide more cultivated land, lessening the contradiction between people and land and achieving the greatest economic benefit, but also attend to social and ecological benefit and produces the maximization of social welfare. However, for lack of thinking about the natural conditions, land consolidation in drought and semi-drought area encounters the problem of cost extension, not achieving Pareto Optimum. Applying theories of welfare economics, this paper analyses the negative exterior effects of land consolidation in terms of theory and practice and puts forward some countermeasures.
