Abstract:

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.
