城镇化进程中土地资源生态破坏经济损失

随着城镇化水平的提高,土地资源的生态破坏加剧,造成了巨大的经济损失.根据土地资源生态损失的特点,可将其分为有效生态损失、环境损失和恢复费用3部分,并分别研究了这3部分损失的评估原则和技术,提出了土地资源生态破坏经济损失定量化的模式.对重庆市万州区的研究表明:万州区1996-2001年城镇化过程中土地资源破坏的总生态损失为34 469.96万元,占2001年GDP的4.70%,总体上土地破坏的经济损失是不断增大的,因此,城镇化建设导致的土地生态破坏问题是不容忽视的.

Economic Loss Assessment of Ecological Damage of Land Resources in the Process of Urbanization:A Case Study of Wanzhou District, Chongqing City

With the improvement of urbanization's level, the destroys of land resources become severer and severer, and the expense is huge. According to their features, land resources can be classified as environmental loss, available ecological loss and land restoration costs. By studying the principle and technique of evaluating these three losses, we put forward quantification pattern of ecological loss of land resources. The research of Wanzhou district, Chongqing city indicates that the number of total ecological loss of land resources during the urbanization from 1995 to 2001 is about 344.70 millions yuan, it is 4.70% of GDP in 2001. In the mass, Wanzhou district is not in a sustainable development because the ecological loss of land resources during the urbanization continually increased.
