摘　　要：应用能值分析方法,选取固碳制氧、土壤肥力保持、表土生成、涵养水源、生物多样性的保护5项因子,以山东省淄博市窑峪流域与花林流域土地整理项目为例,对土地开发整理前后自然环境系统输出的无偿能值变化情况进行分析,研究土地开发整理的生态效益.结果表明,两个项目区土地开发整理的生态效益为正值,但由于大面积开发未利用土地,导致植物种类面积的减少,造成O2的释放、CO2的吸收及生物多样性的能值减少.分析认为,土地开发整理必须将土地生态经济系统与与周围生态环境作为一个有机整体考虑,减少开发,增加整理,注意维护生物多样性.Shandong Zibo YaoYu Basin and HuaLin Basin regional land consolidation project were chosen for empirical research.Solar energy of ecological factor before and after land consolidation was calculated and eco-efficiency of land consolidation was studied with the emergy theory.O2 release and CO2 absorption,soil conservation,surface soil formation,water source self-restraint and biodiversity protection were selected as five factors.The results indicated that ecological profits of land consolidation were improved.On the other hand,large uncultivated land has been developed in the project area,causing a decrease of plant species in the area.As a result,the energy value of O2 release,CO2 absorption and biodiversity is reduced.From the results,we propose that,the uncultivated land development be reduced,the land consolidation be increased,the biodiversity be protected and the ecological and economic systems be taken as whole in land exploitation and consolidation.
