  1. 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
