小区绿化的监管链接——谈小区绿化及管理的若干问题     

丁岚 《农业科技与信息》2009,(7)

房地产开发商作为小区的建设者,与小区的设计、施工、后期管理都产生着直接联系,也只有他,才能行使甲方的权利,对小区的建设有决策权。在小区环境的美化建设中总存在着若干的细节问题,必须提前考虑。只有这样,才能使小区的建设更趋于完美,使小区的功能发挥得更加完整。  相似文献   

对乡镇财政管理现状的调查和思考     

余波  李肖红  杨燕 《农机具之友》2010,(11):39-42

乡镇财政作为政府的一级财政,财政职能不断扩大,工作任务繁重,但乡镇财政队伍建设却明显落后,跟不上形势的要求。当前,加强乡镇财政队伍建设亟不可待,必须采取有力有效措施,把乡镇财政队伍建设成一支能打苦仗、能打胜仗的队伍。  相似文献

Water availability and abundance of microbial groups are key determinants of greenhouse gas fluxes in a dryland forest ecosystem     

《Soil biology & biochemistry》2015

Forests are considered key biomes that could contribute to minimising global warming as they sequester carbon (C) and contribute to mitigate emissions of the potent greenhouse gases (GHG) including nitrous oxide (N₂O), methane (CH₄) and carbon dioxide (CO₂). Management practices are prevalent in forestry, particularly in dryland ecosystems, known to be water and nitrogen (N) limited. Irrigation and fertilisation are thus routinely applied to increase the yield of forest products. However, the contribution of forest management practices to current GHG budgets and consequently to soil net global warming potential (GWP) is still largely unaccounted for, particularly in dryland ecosystems. We quantified the long-term effect (six years) of irrigation and fertilisation and the impact of land-use change, from grassland to a Eucalyptus plantation on N₂O, CH₄ and CO₂ emissions and soil net GWP, within a dryland ecosystem. To identify biotic and abiotic drivers of GHG emissions, we explored the relationship of N₂O, CH₄ and CO₂ fluxes with soil abiotic characteristics and abundance of ammonia-oxidizers, N₂O-reducing bacteria, methanotrophs and total soil bacteria. Our results show that GHG emissions, particularly N₂O and CO₂ are constrained by water availability and both N₂O and CH₄ are constrained by N availability in the soil. We also provide evidence of functional microbial groups being key players in driving GHG emissions. Our findings illustrate that GHG emission budgets can be affected by forest management practices and provide a better mechanistic understanding for future mitigation options.  相似文献   

Management zone delineation using a modified watershed algorithm     

Pierre Roudier  Bruno Tisseyre  Hervé Poilvé  Jean-Michel Roger 《Precision Agriculture》2008,9(5):233-250

Site-specific management (SSM) is a common way to manage within-field variability. This concept divides fields into site-specific management zones (SSMZ) according to one or several soil or crop characteristics. This paper proposes an original methodology for SSMZ delineation which is able to manage different kinds of crop and/or soil images using a powerful segmentation tool: the watershed algorithm. This image analysis algorithm was adapted to the specific constraints of precision agriculture. The algorithm was tested on high-resolution bio-physical images of a set of fields in France.  相似文献
