基于面向对象方法的垦区冲刷沟特征提取研究

Study on Feature Extraction of Erosion Ditch in Reclamation Area Based on Object-oriented Method

黑龙江垦区拥有肥沃的黑土地资源,非常适合大田作物的生长,但是由于过度种植和环境因素等影响,导致垦区坡耕地表被侵蚀现象严重。雨水和山洪的冲刷,致使耕地被破坏,农业生产力下降,威胁农业生产安全,因此,对垦区冲刷沟的形成和冲刷沟生长的监测得到了农业部门的重视。本文利用面向对象的方法,对卫星影像中的冲刷沟进行提取,为黑龙江垦区水土保持工作提供有力的技术支撑。

Heilongjiang reclamation area has fertile black land resources, which is very suitable for the growth of field crops. However, due to the influence of over planting and environmental factors, the surface of slope tillage in the reclamation area is seriously eroded. Due to the scouring of rain and mountain torrents, the cultivated land is destroyed, the agricultural productivity is reduced, and the safety of agricultural production is threatened. Therefore, the agricultural department pays attention to the monitoring of the formation and growth of erosion ditch in reclamation area. In this paper, the object-oriented method is used to extract the erosion ditch in satellite images, which provides strong technical support for soil and water conservation in Heilongjiang reclamation area.
