Area Of ​​reasonable Evaluation In Highway Construction

The land problem is of vital importance to a nation' s safety and the society stability and realizing the sustainable development of land resource is one of the basic factors for the economic and society sustainable development of China in the 21st century; Meanwhile, highway construction is one of the infrastructures of the national economy and its development is the fundamental condition to improve the national economy and to raise the people's living standard, which is also one of the basic factors for the economic and society sustainable development. The heavy occupation of land resource and the bad effects on the land quality produced in the highway construction have caused greater pressure on the land and tilled land resource and it is an urgent matter, which we have to face, to work out a solution to settle the problem of highway development and occupation of land into a compatible developmental course. However, this problem, which involves the coordination of resource, environment and development, has still not been attached high importance to.In combination with the rapid development of highway construction and the present severe situation of tilled land and land resource, effects on economy, society and resource produced by highway construction are approached from three different angels: the improvement to the economy and society development, the peculiarities and the severity of occupation of land resource and the bad effects on land use caused by soil and water loss, thus arousing the people to pay high attention to the occupation of land resource in highway construction. A method of cost-benefit analysis is approached to evaluate the economic rationality of occupation of land in highway construction and the social benefits produced by highway construction are analyzed qualitatively; At last, these methods are tested and verified through a concrete engineering in Yangling Agricultural Hi-tech Demonstrational Zone and effective technological and systematic measures are put forward in order to settle the problem onto a compatibly developmental path.
