摘要
采用"3S"技术与地面调查相结合,并以地面调查为主的技术路线,开展了河南省第1次岩溶地区土地石漠化状况监测,涉及10个县(市)、79个乡(镇、林场、街道办事处)、580个行政村。监测结果表明:石漠化土地面积74 647.7 hm2,占岩溶土地面积的27.88%;潜在石漠化土地面积93 102.2 hm2,占岩溶土地面积的34.77%。石漠化防治形势十分严峻,必须加大该区域石漠化综合治理力度,确保岩溶地区的生态环境得到有效修复,实现生态与经济的协调发展。
In the use of technical route combining ＂3s＂ technology and ground survey and giving the priority to ground survey, we carried out the first monitoring on the present situation of stony desertification in karst region of Henan which related to 10 counties, 79 townships and 580 villages.According to the monitoring, the area of stony desertification is 74647.7 hectares which accounts for27.88% of the tatal area of karst region and potential stony desertification 93102.2 hectares which accounts for 34.77%.
