河北省农业可持续发展长期以来受人口、制度等因素制约,为避免这些因素所带来的负面效应,同时寻找出适合河北省农业可持续发展之路,亟需建立较全面的、准确的关于河北省农业可持续发展能力的评价指标体系,为河北省的农业可持续发展提供数量依据。文章在明确影响河北省农业可持续发展因素的前提下,从农村人口发展水平、农业经济生产发展水平、农业社会可持续发展水平、农业科技发展水平、农业资源利用水平、农业生态环境质量等方面构建河北省农业可持续发展水平评价指标体系,并在分析农业生态系统可持续发展度的基础上提出加强资源、环境的保护与合理利用,提高科技水平、实施科技兴农战略;控制人口数量、加快劳动力的转移,完善相关法律、建立政府支持政策等方面对策措施,以促进河北省农业经济的可持续发展。  相似文献

Pastoral landscape woody vegetation provides ecosystem services, but potentially competes for space, light and nutrients that could provide additional farm production. A questionnaire determined the values and behaviours of New Zealand dairy farmers to evaluate voluntary agri-environmental programmes for restoring woody vegetation. Findings indicate the area is increasing, while the composition and configuration of networks are changing and redistributing. Farms with little are losing more, and those with more are gaining. Farmers are planting new areas to increase their public ecosystem services, but may not provide these services through planting and management. Barriers include insufficient private woody vegetation ecosystem services, and low rates of growth of native plants. Government incentive programmes are ineffective in overcoming barriers. Farmers may be motivated by stronger evidence of valued ecosystem services, information about their benefits and drawbacks and how to support services through planting and management. However, a targeted environmental stewardship scheme is required to overcome barriers to planting, with government and the dairy industry working together to develop and maintain a landscape-scaled woody vegetation network on private and public land. Such networks would build sustainability and resilience into dairy farming, leading to an equitably sharing of benefits and costs of their public ecosystem services.  相似文献

Industrial meat production has several negative environmental effects. Governments’ agricultural policies aim for cost efficiency combined with high environmental and animal welfare, which puts farmers in a difficult situation trying to navigate between sometimes contradictory requirements. This paper studies how Swedish pig farmers resolve or cope with conflicting goals in pig farming. We have analysed the regulations governing EU and Swedish pig farming. We have also interviewed five Swedish pig farmers about their views of the different goals of pig farming and strategies for resolving conflicts between the goals of low environmental impact, high animal welfare and enough profitability to continue farming. The greatest divide was between the conventional farmers, who emphasized natural resource efficiency, and the organic farmers who stressed animal welfare, multifunctionality and ecosystem service delivery. We suggest four strategies to contribute to resolving some of the conflicting goals: improve communication about different types of pig farming; use public procurement as a driver towards more sustainable pork production; work towards improving the Common Agricultural Policy, perhaps by implementing payments for ecosystem services or multifunctionality; and finally, decrease the total production of pork to lower the emissions per land unit.  相似文献

该研究借助遥感与GIS技术,考虑影响农业生态系统的关键因素,选取植被指数、地表温度、降水距平以及自然灾害等主要指标,建立了我国农业生态评价的指标体系。根据研究所提出的指标体系以及评价方法,开展了2006年3月上旬到10月上旬的全国农业生态综合评价,并详细分析了每个月我国各地区的生态状况,结果表明我国2006年农业生态总体状况比较好,只有个别地区比较差。该研究所提出的基于遥感与GIS的农业生态指数评价方法,可以及时有效地获取全国范围内农业生态系统状况,而且可以考虑长期业务化运行,它将能为全面掌握我国农业生产状况,保障我国农业平稳发展有非常重要的意义。  相似文献
