大石桥市东、中部矿产资源丰富,矿产资源开发成为该市经济发展的支柱产业。但随着矿产资源开发的迅猛发展,也产生了大量的水土流失。大石桥市东、中部低山、丘陵区面积为1026.13km2,占土地总面积的63.69%,是水土保持重点监督区和重点治理区;西部平原区面积为584.67km2,占土地总面积的36.31%,是重点预防保护区。据第4次辽宁省土壤侵蚀遥感普查,大石桥市现有水土流失面积比2000年全省第3次遥感普查成果相比,水土流失面积减少51.4km2,但轻度侵蚀、剧烈度侵蚀强度却升级。面对如此严峻的生态形势应采取科学规划、综合治理、科学监测等有效措施,积极防治水土流失的发生和蔓延,实现生态环境的可持续性发展。
Dashiqiao City, east, central rich in mineral resources, mineral resources development has become the city’s economic development pillar industries. However, with the rapid development of mineral resources, a great deal of soil and water loss has also occurred. Dashiqiao City, east, central low mountain, the hilly area of 1026.13km2, accounting for 63.69% of the total land area, is the key monitoring area of water and soil conservation and key governance area; western plains area of 584.67km2, accounting for 36.31% of the total land area, , Is a key prevention and protection zone. According to the 4th Remote Sensing Survey of Soil Erosion in Liaoning Province, compared with the results of the third remote sensing survey in 2000 in Dashiqiao City, the area of soil erosion has decreased by 51.4km2. However, mild erosion and intense erosion intensity upgrade. Faced with such a severe ecological situation, we should take effective measures such as scientific planning, comprehensive management and scientific monitoring so as to prevent and control the occurrence and spread of soil and water loss and achieve the sustainable development of the ecological environment.
