【摘要】：[目的]引用俞孔坚的景观安全格局理论,借助Arc GIS10、Conefor Sensinode2.2和In VEST2.2.0制图软件构建青龙满族自治县景观生态安全格局,针对景观生态安全格局各组分的分布特点,提出相应的生态规划对策,以期为青龙满族自治县维护生态系统稳定、合理进行生态规划提供借鉴。[方法]首先,综合考虑斑块自身特征属性和外界环境因素,通过景观斑块质量评价来识别源地;其次,根据最小累积阻力模型构建最小累积阻力面并划分为3个最小累积阻力等级,分别对应生态保育区、生态防护区和生态培育区3个生态功能区;最后,确定生态廊道和战略点。[结果]源地占研究区总面积的3.59%,源地内耕地、园地、林地、草地、水体所占比例分别为0.14%、0.25%、66.86%、17.21%、15.54%;生态保育区占研究区总面积的34.98%,生态保育区内耕地、园地、林地、草地、水体、其他用地所占比例分别为6.73%、8.69%、49.32%、29.57%、3.40%、2.29%;生态防护区占研究区总面积的36.40%,生态防护区内耕地、园地、林地、草地、水体、其他用地所占比例分别为10.31%、18.57%、37.68%、26.67%、1.87%、4.91%;生态培育区占研究区总面积的28.62%,生态培育区内耕地、园地、林地、草地、水体、其他用地所占比例分别为11.31%、15.57%、39.80%、26.70%、2.28%、4.34%;沿景观低阻力区分布有7条生态廊道;有8个战略点。[结论]文章所构建景观生态安全格局基本符合青龙满族自治县实际情况,各景观生态安全格局组分有不同的特点,对应有相应的生态规划对策。
[Abstract]:[Objective] reference landscape security pattern theory of Yu Kongjian, with the help of Arc GIS10, Qinglong Manchu Autonomous County landscape ecological security pattern construction of Conefor Sensinode2.2 and In VEST2.2.0 software, according to the distribution characteristics of each landscape ecological security pattern points, put forward corresponding countermeasures ecological planning, in order to maintain the stability of the ecosystem of Qinglong Manchu Autonomous County, to provide a reference. The first method is reasonable ecological planning, comprehensive consideration of patches characteristic properties and environmental factors, the landscape quality evaluation to identify the source; secondly, according to the minimum cumulative resistance model minimum cumulative resistance surface is divided into 3 levels corresponding to the minimum cumulative resistance, ecological conservation areas, ecological protection zone and ecological cultivation area of 3 ecological function finally, to determine the area; ecological corridor and strategic point. The source of the total area of the study area in 3.59%, the source of cultivated land , garden, woodland, grassland, water accounted for 0.14%, 0.25%, 66.86%, 17.21%, 15.54%; ecological conservation areas accounted for 34.98% of the total area of the study area, ecological conservation area of arable land, garden land, woodland, grassland, water and other accounts for the proportion of land use were 6.73%, 8.69%, 49.32%, 29.57%. 3.40%, 2.29%; ecological protection area accounted for 36.40% of the total area, ecological protection area of cultivated land, garden, woodland, grassland, water and other accounts for the proportion of land use were 10.31%, 18.57%, 37.68%, 26.67%, 1.87%, 4.91%; ecological cultivation area accounted for 28.62% of total area, ecological cultivation area farmland, garden, woodland, grassland, water and other accounts for the proportion of land use were 11.31%, 15.57%, 39.80%, 26.70%, 2.28%, 4.34%; distribution along the low resistance region has 7 landscape ecological corridor; there are 8 strategic points. Conclusion] in this paper the landscape ecological security pattern accords with the actual situation of Qinglong Manchu Autonomous County The components of the landscape ecological security pattern have different characteristics, and corresponding ecological planning countermeasures are corresponding.
