通过对小华山丘岗红壤“林、果、经、肥”、“经、肥旱作”、“单一果园”三种农业生态系统功能的分析表明:“林、果、经、肥”系统和“经、肥旱作”系统在小气候效应、土体养分积累与流通、能量转换等方面都优于“单一果园”。说明在某一生态系统中参与的因子越多.结构越复杂,则该系统的功能越强.抵御外界灾害的能力也越强。但是.这三种农业生态系统仍只限于种植业,使物质、能量的利用和转化受到限制.应在此基础上,结合发展畜牧业和养殖业,建造“林、果、农、牧”以及“林、果、农、牧、加”等更趋合理优化的生态农业模式。
Through the analysis of the functions of three agroecosystems in Xiaohong hilly red soil “forest, fruit, by, fertilizer”, “by, fertilizer and drought”, “single orchard” The system of “fertility and drought” is superior to “single orchard” in terms of microclimate effects, soil nutrient accumulation and circulation, energy conversion and so on. The more factors involved in an ecosystem, the more complex the structure, the more powerful the system is and the better it can withstand external disasters. However, these three kinds of agro-ecosystems are still limited to the farming industry, which limits the utilization and conversion of materials and energy, and on this basis, should combine the development of animal husbandry and aquaculture to build “forest, fruit, agriculture and animal husbandry” and “Forest, fruit, agriculture, animal husbandry, plus” more rational and optimized ecological agriculture model.
