摘　　要：基于遥感技术核查水泥企业违法开工建设,有助于环境监察部门及时制止环境污染行为,保护生态环境。选择石家庄地区作为研究区,分析将遥感技术应用于核查水泥企业违法建设行为的可行性,并提出不同核查任务下的最低影像分辨率需求。为实现此目的,首先,选择不同规模代表性水泥企业,开展遥感解译特征分析,建立解译知识库;其次,研究不同规模水泥企业遥感解译标志在不同分辨率遥感影像下的可识别性;最后,根据不同核查任务的特点,提出各任务对影像分辨率的需求。结果表明:(1)煅烧设施、生料贮库、熟料贮库、水泥贮库、联合贮库、原料贮存场是水泥厂遥感识别的重要标志;(2)对于批小建大行为、正在建设的未批先建行为的遥感核查,最低影像分辨率需求为大、中型企业1.0m全色影像,小型企业0.5m全色影像;(3)对于重点区域已建成未批先建行为的遥感核查,最低影像分辨率需求为大型企业2.0m全色影像,中型企业1.0m全色影像配合3.0m多光谱影像,小型企业0.5m全色影像配合3.0m多光谱影像;(4)对于非重点区域已建成未批先建行为的遥感核查,最低影像分辨率需求为大、中型企业3.0m多光谱影像,小型企业2.0m全色影像配合3.0m多光谱影像。Using remote sensing technology for illegal cement enterprise detection was useful to help environment supervised department to prevent pollution behaviors and to protect the ecological environment.Taking Shijiazhuang city as a research area,the feasibility for cement company inspection base on remote sensing technology was analyzed,and the least geometric resolution requirement of image for different detection assignments was proposed in this study.For this purpose,firstly,different scale representative cement enterprises were selected.They were used to analysis identification characteristics of cement company using remote sensing,and then format interpretation knowledge.Secondly,the feasibilities of identification of recognition features of different scale enterprises were analyzed,with different remote sensing geometric resolution images.Finally,the least geometric resolution requirements of image for different remote detecting assignments were suggested according to their features.The results showed：（1）The calcining facility,raw material reservoir,clinker reservoir,cement reservoir,joint reservoir,raw materials field were the important remote sensing recognition features of cement company;（2）The least geometric resolution requirement of image for detection behaviors of illegal enlarge the scale and under construction without permission were 1.0m panchromatic image for large and medium company,and 0.5mpanchromatic image for small company;（3）The least geometric resolution requirement of image for behavior of construction without permission were 2.0mpanchromatic image for large scale company,and 1.0mpanchromatic image with 3.0m multispectral image for medium scale company,and 0.5mpanchromatic image with 3.0m multispectral image for small scale company in sensitive area;（4）The least geometric resolution requirement of image for behavior of construction without permission were 3.0m multispectral image for large and medium scale company,and 2.0 mpanchromatic image with 3.0 m multispectral image fo
