摘要
应用GIS软件ArcView绘制黄塔小流域景观生态类型分布图,并选取了7个具有代表性的指标对小流域的景观格局进行了详细的分析。在收集和广泛调查的基础上,分析小流域农业发展状况、立体结构及投入产出分析,提出治理小流域的措施:调整农业产业结构、充分利用土地,搞好小流域综合、立体开发。最后指出,小流域景观格局是自然和人类活动综合作用的结果,在不同部位人类活动与自然因素的作用强度不同,并且人类活动的空间扩展趋势明显;在短期内人造景观的稳定性高于自然景观,但远离均衡状态。表7,参9。
Landscape type distribution map of Huangta small watershed was drawn with the ArcView of GIS software. The landscape pattern of the small watershed was analyzed by the selected seven representative indices. Based on data collection and extensive investigation, situations of development, structure and input-output of agriculture in the small watershed were assessed. Measures of management are put forward for the small watershed： adjust agricultural industry structure, sufficiently use land resources, exploit it comprehensively. It was showed that landscape pattern of the small watershed was affected by beth nature and human activities. Interaction intensity beteween nature and human activities varied in different position of the small watershed, and the range influenced by human activity is extending obviously. Stability of artifical landscape is higher than natural one in a short time, but it is far away from equilibrium.
