摘　　要：为缓解经济发展和人口的日益增长与耕地面积和质量下降的矛盾,对河北省开展可持续土地整理十分必要。该文针对河北省土地资源和地形地貌特征,分析了河北省可持续土地整理模式,在此基础上通过生态服务功能的货币化,定量计算土地整理前后项目区的生态服务价值,评估不同的土地整理模式下的经济价值和生态服务价值损益,探究不同土地整理模式的效益。主要结果有:河北省可持续土地整理典型模式包括土地平整模式、灌溉模式和排水模式;除耕地外其他5种类型(园地、林地、水域、湿地、荒草地)的总土地生态服务价值随经济价值增加而减少;单项的生态服务功能有四项功能(食物生产、土壤形成与保护、原材料价值、气体调节)价值保留并增加,五项功能(水源涵养、废物处理、气候调节、娱乐文化价值、生物多样性保护)价值大大减少,总土地生态服务价值因此亏损严重;低山丘陵区的土地整理项目经济价值提高小,生态价值损失大;而高原区土地整理项目能够明显提高经济效益,但以牺牲更高生态价值为代价。主要研究结论为:可持续土地整理项目总体可获益,即经济效益的增加大于生态效益的减少,但仍以生态服务价值为代价取得更多的经济效益;平原区土地整理效果好于低山丘陵区和高原区,土壤状况差的耕地土地整理效果显著;需要根据不同的地形特征条件因地制宜地规划土地利用类型,除耕地外,其他用地更要注重其生态服务价值。In order to relieve the conflict of increasing economy and population and decreasing land quantity and quality, it is necessary to carry out land consolidation planning from the aspect of sustainable develop- ment, particularly in Hebei Province where grain and cotton of China are mainly produced. Based on land re- sources and topography and geomorphology characteristics in Hebei Province, sustainable land consolidation pattern in Hebei Province was identified. The ecosystem service value before and after the land consolidation was calculated by monetizing the ecosystem service functions. Effect of different sustainable land consolida- tion pattern was explored by the economic value and ecosystem service value evaluation. The typical pattern of land consolidation project included land leveling mode, irrigation mode, and drainage mode. Ecosystem service values of 5 land use types （garden, woodland, grassland, wetland, water area） other than farmland were decreasing with the increase of economic value. Four of individual ecosystem service functions （food production, soil formation and protection, the value of the raw materials, gas regulation） values retained and improved while five of them （water conservation, waste treatment, climate regulation, recreational and cul- tural value, biodiversity conservation） reduced a lot. The ecosystem service value of land therefore severely lost. The economic value of land consolidation in the hilly region improved little while its ecosystem value decreased a lot. The economic value of land consolidation in the plateau area improved a lot by service paying the price of the ecosystem service value. The mainly conclusions were as followings, the sustainable land consolidation project of Hebei Province totally benefits. The improvement of economic benefits, in other words, was larger than the decrease of ecological benefits. But it was always replaced more economic benefits with the cost of ecosystem services value. Land consolidation of the plain area was more effectiv
