Land consolidation (LC) is essential for ensuring rural development and for increasing land use effectiveness. LC has been implemented in China since the mid-1990s in an attempt to increase available cropland area, reduce fragmentation and promote agricultural production capacity. The purpose of this study is to identify the changes resulting from the land consolidation project (LCP) implementation, and to develop a parametric approach to assess the resource–environment effects. This study could promote the LCP planning, and provide the support for the decision-making of the LC authorities. The Tianmen land consolidation project in Hubei Province of China was chosen as a case study. The results of the case study showed LCP implementation results in great changes in land use types and their proportions, connectivity of field-roads, irrigation systems and drainage systems, plot numbers, plot shape and plot size. These changes bring both positive and negative effects to region environmental and economic system. Positive effects were demonstrated in agricultural production capacity and agricultural production cost and the negative effects were expressed by the ecosystem services value, landscape diversity and human disturbance intensity.

土地整治所引发的变化及其资源环境影响

土地整治是保证农村发展和提高土地利用效率的有效工具。自上个世纪90年代中期,中国开始实施土地整治,用以增加耕地有效利用面积、减少土地破碎化和提高农业综合生产能力。论文的目的在于识别土地整治所带来的变化,并建立参数评价方法对这些变化所产生的资源环境影响进行评估,这种评价方法既可以作为一种预评价用在土地整治前,用来指导土地整治项目规划设计或者用来选择适合整治的区域;也可以作为一种后评价用在土地整治后,用来判断土地整治目标的实现程度,从而为政府部门的土地整治决策提供依据。论文以湖北天门为例进行了案例研究,研究结果表明,土地整治的实施导致了土地利用类型结构、道路和灌排系统连通度、田块数量、田块规模等的变化,这些变化产生了正向和负向的影响。正向的影响表现为农业生产能力的提升和生产成本的降低。负向影响表现为生态系统服务价值的降低和景观多样性的减少。
