【摘要】：为了分析研究海流兔河流域生态环境变化以及人为因素和自然因素在区域中各自影响,文中通过计算实际的NPP和潜在的NPP的方法来分离人为因素和自然因素各自所占比例。结果表明:1)研究区多年来植被生态环境呈现出良性的发展;2)在时空变化中,人为因素占到影响区域的85.9%,是该区域生态环境良性发展的主要推动力;3)在区域空间变化中,人类活动影响较大的区域主要集中分布在河床谷地以及湖盆滩地地区,自然因素影响较大的区域主要集中分布在沙丘沙地以及流域分水岭和河岸两边的沙梁地区。人为因素和自然因素共同促进了该区域的生态环境发展,人为因素是该区域生态环境良性发展的主要推动力。
[Abstract]:In order to analyze the change of ecological environment and the influence of human and natural factors in the basin, the actual NPP and potential NPP were calculated to separate the proportion of human factors and natural factors. The results show that the vegetation ecological environment in the study area has shown a positive development for many years. In the temporal and spatial changes, human factors account for 85.9% of the affected areas, which is the main driving force for the benign development of the ecological environment in the region. The regions which have a great influence on human activities are mainly distributed in the riverbed valley and the beach area of the lake basin, and the regions which have a great influence on the natural factors are mainly distributed in the sand dunes and the watershed and the sand beam area on both sides of the river bank. Human factors and natural factors promote the development of ecological environment in this region, and human factors are the main driving force for the benign development of ecological environment in this region.
