摘要
针对近年山东省种植业和养殖业生产现状,以种植业废弃物资源产生量、养殖饲料需求量、养殖业废弃物产生量、养殖废弃物农田消纳限量为依据,根据资源利用最大化和环境影响最小化原则,分析山东省种植与养殖结构优化配置量化关系。结果表明,在现有沼气工程数量和耕地面积下,目前山东省的剩余有机废弃物农田消纳环境容量为8588万t,其中聊城市和临沂市的剩余空间较大,泰安市、济宁市、菏泽市、枣庄市、青岛市、潍坊市、烟台市也有较大的消纳空间,德州市、日照市、东营市都超过其自身消纳能力,其中东营市更是超过其自身消纳水平的30%。说明尽管目前山东省农田对畜禽养殖业所产生的有机废弃物有一定的消纳空间,但各地市之间存在明显的地区差异,这为今后山东省种养结合的优化发展提供理论依据。
According to the planting and breeding production status in Shandong Province in recent years and the principles of resource utilization maximization and the environmental impact minimization, the quantitative relationship between planting and breeding structure optimization configuration of Shandong Province was analyzed in the paper, based on planting waste resources quantity, breeding feed demand, aquaculture waste quantity and the limited quantity of animal waste disposal by farmland. The results indicated that, the residual environmental capacity of farmland absorptive organic waste of Shandong Province was 85.88 million tons with the existing biogas engineering quantity and the cultivated land area; and the residual environmental capacities of Liaocheng City and Linyi City were bigger, then Tai＇ an City, Jining City, Heze City, Zaozhuang City, Qingdao City, Weifang City and Yantai City, while those of Dezhou City, Rizhao City and Dongying City were more than the limited abilities, and Dongying City was more than its own level of 30%. Although current farmland of Shandong Province had certain absorptive space for the organic waste from livestock and poultry breeding industry, but the status of every city was different, so this could provide the theoretical basis for planting-breeding combination and its optimized development of Shandong Province in future.
