兖州矿区复垦农田景观格局演变过程研究

Study on evolvement process of landscape pattern of reclaimed farmland in Yanzhou mining area

通过对兖州矿区农田在采矿前后、复垦前后的景观格局变化情况的分析,进一步认识煤矿开采沉陷与农田景观过程的关系以及规划设计、施工与景观格局和过程的关系,揭示了复垦农田景观演变的一般规律,提出了复垦农田景观重建方法与重建标准.得出如下主要结论:科学技术发展要求农田景观格局与其适应,演变是农田持续发展的需要;采矿条件是影响矿区农田景观格局的主要因素,积水、坡地、裂缝是开采后农田景观主要格局;生产力保持稳定和提高、景观格局与环境保持协调、降低农田基质恢复期等是复垦农田景观重建的重要标准.

Analysed the landscape pattern changes before and after coal mining, before and after reclamation in Yanzhou mining area.Further realize the relationship between subsidence due to coal mining and farmland landscape process, and the relationship between the plan design, the construction and the pattern and process of the farmland landscape, revealed the general laws of the landscape evolvement in the reclaimed farmland, proposed the methods of the landscape reconstruction and the reconstruction standards of the reclaimed farmland. Obtained following conclusions:the farmland landscape pattern must meet the demand of the development of science and technology, evolvement is demand of farmland sustainable development; mining condition is the main factor that affect the farmland landscape pattern; storing water, slope land, crack are the main the farmland landscape patterns after coal mining; keeping and improving farmland productivity, landscape pattern harmony with environment,reducing the period of farmland matrix restoration, etc are main standards of the reclamation farmland pattern reconstructions.
