在中国农业大学曲周实验站设置了优化施肥(CK)、优化施肥添加蚯蚓粪(VC)和优化施肥添加生物有机肥(MOF)的田间试验,测定了夏玉米产量,并动态监测了玉米拔节期、大喇叭口期、抽雄期和收获期地上部生物量、土壤有效磷和矿质态氮、有机质和微生物量碳的变化,并计算了氮肥效率。结果表明,施用蚯蚓粪和生物有机肥产量分别比优化施肥(CK)提高了6.8%和8.2%。在整个生育期内,施用生物有机肥的处理土壤有效磷含量显著高于对照处理,是增产的主要因素;施用蚯蚓粪的处理在作物生长的中后期对土壤微生物量碳的调节作用十分显著,对作物增产意义重大。添加蚯蚓粪和生物有机肥能够提高氮肥的利用效率,减少施氮量,应用前景广阔。

建设生态省是实施区域可持续发展的一种有效组织形式。本文就国家环保总局批准的七个生态示范省的经济发展及区域可持续发展能力进行比较,发现七省的经济发展现状及区域可持续发展能力在全国31个地区中属于中上水平,均有创建生态省的本底条件,但区域可持续发展各方面的能力极不平衡,各省要从实际出发,扬长避短,因地制宜,探索具有本地特色的生态省建设的新路子。

流域综合管理是解决流域性生态环境问题的主要途径。评估流域综合管理对当地社区和农民生产生活影响一直是流域综合管理领域的研究热点。以我国黄土高原世界银行贷款项目区中的小流域综合治理项目为研究对象,从项目区总体社会经济发展和微观层面的农户收入2个方面对流域综合管理项目的实施效果做了相应分析。结果表明治理项目促进了当地社区的社会经济发展,从微观层面的农户收入影响分析表明流域综合治理项目是重要的影响因素。在此基础上,该文提出了相应的政策建议。
