摘要
通过分析开封沙区农林牧复合生态经济系统的构建与调节措施,进而系统地探讨了系统功能的主要特征,结果表明系统的生产能力不断提高、人均收入不断增加、农田物质投入不断改善,但K素亏缺和产业结构不平衡等问题依然存在。并总结了沙区农林牧复合生态经济系统发展的经验。
The foundation and its adjusting methods of farming-forestry-animal husbandry compound ecosystem in Kaifeng sandy experimental region are analyzed, and the characteristics of the system are stated. The results show that the ability of biological production has been improved, the income per person is getting more and more, and the input of material and energy of field system is getting better and better. However, there still exist the shortage of potassium and the unbalance of production structure. Finally, the experiments and methods of the system development are suggested.
