在中国,主要的农林复合经营系统占地大约4500万 hm~2。主要的经营模式是农林复合经营。淡水养殖林业复合经营如林-渔-次作物及林-渔-畜禽复合系统是湿地的土地利用方式。林牧复合系统在北部和西部地区很普遍。与单一栽培模式相比,经营良好的系统会产生许多效益。残留物的再循环可望能提高自然资源的有效利用。中国主要的农林复合经营系统中植被的碳汇达179Tg/a。据报道,农林复合经营对土壤保护和生物多样性有积极的影响作用。限制农林复合经营的主要因素在于因缺少技术支持而使大多数系统管理水平低下。尽管如此,中国农林复合经营具有巨大的发展潜力。本文提出了一些农林复合经营中有关政策取向、技术支持、推广及市场开发的建议。
In China, the major agroforestry system covers an area of about 45 million hm 2. The main business model is agroforestry. Freshwater aquaculture forestry compound management such as forest - fishing - crops and forest - fishing - livestock and poultry complex system is the wetland land use. Lam Fung composite system is common in the northern and western regions. A well-run system produces many benefits when compared to monoculture. Recycling of residues is expected to enhance the efficient use of natural resources. The carbon sequestration in China’s major agroforestry systems is 179 Tg / a. It has been reported that agroforestry has a positive impact on soil conservation and biodiversity. The main factor limiting agroforestry is the low level of most systems management due to a lack of technical support. However, China’s agroforestry has great potential for development. This paper puts forward some suggestions on policy orientation, technical support, promotion and market development in the agroforestry business.
