| 中文摘要: |
| 以松嫩平原西南部的长岭县为例,依据区域农业可持续发展理论、生态经济学、反馈控制理论和系统动力学原理,建立干旱半干旱区农业生态环境系统动力学模型。设计了“维持现状”、“生态建设”、“节水”、“偏畜牧业”、“偏种值业”和“农牧互促”等6种调控方案。经仿真模拟及其结果对比分析,“农牧互促”方案是研究区农业生态系统的优化调控方案。 |
| 英文摘要: |
| Taking Changling County in south-west Songnen Plain as an example,with the principles of regional agriculture sustainable development,ecological economics,feedback control theory and system dynamics,the article sets up the model of optimal adjustment for agricultural eco-environment system in arid and semi-arid regions.Six adjustment schemes are designed,including present trend maintaining,ecological constructing,water saving,leaning to stockbreeding,leaning to farming,and farming and stockbreeding promoting.The simulating results show that the scheme of farming and stockbreeding promoting is the best adjustment scheme for agricultural eco-environment system in arid and semi-arid regions. |
