为了定期准确掌握烟台经济技术开发区沙化土地的现状以及动态变化,开展了第六次沙化监测,为上级制定规划和治理提供依据。本文采用ArcGIS软件和全国荒漠化和沙化监测系统开展了内业图斑区划和外业实地调查,形成了2019年本期成果数据;介绍了本期沙化土地类型、沙化程度、土地利用类型、沙化治理程度等现状,并通过前期数据与本期数据进行比对,进一步分析了监测区内各类土地的动态变化以及引起相应变化的原因,即与前期相比,本期全区流动沙地和极重度沙地面积都明显减少,沙化程度显著降低;最后提出了治理建议。

The sixth monitoring and analysis of desertification land in Yantai Economic and Technological Development Zone

The purpose of carrying out the sixth desertification monitoring is to accurately grasp the current situation and dynamic changes of desertification land in our district on a regular basis, so as to provide a basis for superiors to formulate plans and control. In this paper, arcgis software and the national desertification and desertification monitoring system were used to carry out internal industry map spot zoning and field investigation, forming the data of this period. This paper introduces the current situation of desertification land type, desertification degree, land use type and desertification management degree in this period, and further analyzes the dynamic changes of various types of land in the monitoring area and the reasons for the corresponding changes through the comparison between the preliminary data and the current data. Compared with the previous period, the area of flowing sand and extremely heavy sand in this period is obviously reduced, and the degree of desertification is significantly reduced. Finally put forward the management suggestion.
