| 中文摘要: |
| 以宁夏南部半干旱黄土丘陵侵蚀退化区生态系统内部土地资源适宜性评价及合理配置与系统优化研究为核心,探讨了研究地区生态恢复与生态农业体系建设的基本途径。研究将系统土地资源总体划分为4个一级类、10个二级类和10个三级类。根据土地对作物生长限制生态因子的多少和程度,综合评价土地的适宜性,并将其划分为8个顺序等级。遵循人-地制约关系的基本原则,应用系统工程学的理论和方法对系统进行优化设计和建模,并在生产中实施,取得了良好的综合效益。同时就该地区生态恢复与生态农业体系构建,区域化生态环境治理及农业产业化过程的关系进行了探讨。 |
| 英文摘要: |
| The study was carried out to constitute the eco-economical agriculture pattern in semi-arid degenerated hilly region of Loess Plateau in southern Ningxia. The theory and practice of classification, adaptability evaluation and optimizing collocation of land resources in eco-economical agricultural systems were investigated. Following the discipline of interaction of land resource and human, applying principles and methods of system engineering, the agricultural production system was optimized. Moreover, the relationship between ecological agricultural construction and territorial management was discussed. |
