- 摘要:
- 生态安全视角下土地利用冲突识别有助于协调生态保护与社会经济发展之间的平衡。基于青龙满族自治县2016年土壤、气象、土地利用等数据,首先,按照识别源地、廊道、缓冲区的步骤构建研究区生态安全格局; 其次,利用GIS空间分析功能,揭示耕地、建设用地与不同等级生态安全用地的空间叠加关系,由此识别生态安全视角下耕地、建设用地、综合用地的土地利用冲突空间分布特征。结果表明:青龙满族自治县土地利用冲突总体分布较为分散,其中耕地极严重冲突区主要分布在祖山镇、龙王庙乡、青龙镇,该类地区为人口密集区,对农产品需求较大,导致耕地对生态安全空间的占用; 建设用地极严重冲突区主要分布在青龙镇、祖山镇、大巫岚镇,该类地区为经济发展密集区,城镇扩展导致建设用地对生态安全空间的占用; 综合土地利用极严重冲突区主要分布在祖山镇、龙王庙乡、青龙镇。针对土地利用冲突高发区,应通过调整土地利用结构、转变经济发展方式等措施达到保障区域生态安全的目的。
- Abstract:
- The identification of land use conflicts from the perspective of ecological security can help coordinate the balance between ecological protection and socio-economic development. Based on the data of soil, meteorology and land use in Qinglong Manchu Autonomous County in 2016, firstly, the ecological security pattern of the research area was constructed according to the steps of identifying the source, corridor and buffer zone; secondly, the spatial overlapping relationship between cultivated land, construction land and ecological security land of different grades was revealed by using the spatial analysis function of GIS, so as to identify the spatial distribution characteristics of land use conflicts of cultivated land, construction land and comprehensive land from the perspective of ecological security. The results showed that the overall distribution of land use conflicts in Qinglong Manchu Autonomous County was relatively scattered; the extremely serious conflict areas of cultivated land mainly distributed in Zushan Town, Longwangmiao Township and Qinglong Town, these areas wer densely populated areas with the large demand for agricultural products, which led to the occupation of ecological security space by cultivated land; the extremely serious conflict areas for construction land mainly distributed in Qinglong Town, Zushan Town and Dawulan Town, these areas were economically intensive areas, and urban expansion led to the occupation of ecological security space by construction land; the extremely serious conflict areas of comprehensive land use mainly distributed in Zushan Town, Longwangmiao Township and Qinglong Town. In view of the high-risk areas of land use conflicts, the measures to ensure regional ecological security should be achieved by adjusting land use structure and transforming economic development methods.
