哈尼梯田遗产地人类活动强度定量化研究

人类活动强度是表征人类对环境影响和作用程度的指标，可通过土地利用类型来定量化。本研究运用地理信息系统 (GIS) 技术，以哈尼梯田遗产地所在的元阳县的土地利用数据为基础，结合研究区实际情况，建立了元阳县不同土地利用类型的人类影响强度系数，量化了研究区域的人类活动强度的大小和空间分异。结果表明元阳县人类活动强度整体较低，但从元阳县到遗产区再到遗产核心区，人类活动强度呈明显的递增趋势。空间上看，元阳县人类活动强度西高东低，高值一般出现在 1500 m-2000 m 的中高海拔地区。遗产区和遗产核心区的人类活动强度则以主要梯田片区为表征，呈块状分布，高值主要集中在牛角寨、坝达、多依树、老虎嘴4大梯田片区。

Quantitative Study on Human Activity Intensity in Hani Rice Terrace Heritage

Human activity intensity is an indicator of human impact on the environment and can be quantified by land use type.This paper established the human impact intensity coefficient of different land use types in Yuanyang County based on the actual situation of the study area.Quantify the size and spatial differentiation of human activity intensity in the study area. The results show that the intensity of human activity in Yuanyang County is low, but the intensity of human activity is increasing from Yuanyang County to the heritage area and the core area of heritage. From a spatial point of view, the human activity intensity of Yuanyang County is high in west but low in east, And the high value generally appear in the 1500-200m middle-high altitude areas. The human activity intensity of the heritage area and the core area of heritage is characterized by massive distribution of several main terraced areas. The high values are concentrated in the Niujiaozhai, Bada, Duoyishu and Laohuzui.
