干旱区绿洲村镇体系景观评价的场景可视化研究——以新疆乌什县为例

Scene Visualization of Rural Landscape Assessment in Arid Area Oasis

通过场景可视化技术,利用图像处理软件模拟在同一背景下不同景观空间特征梯度和不同农业生产模式的场景图片,并通过参与式评估技术,获取新疆阿克苏地区乌什县八乡一镇180名受访者的偏好意愿。通过对调查结果的统计、分析,评价不同利益相关者对村镇体系景观发展趋势的偏好。结果显示:一般来看,绝大多数受访者不愿意选择多样性较强的景观;多数受访者更喜欢破碎度较弱的景观;对于景观聚集度的偏好程度在各个利益群体中的差异都不甚明显;受访者通过场景图片更加偏好菜地景观,而通过语言和理性思考后则更倾向于选择农田景观。受访者因年龄、自身文化程度、收入、农业生产所占收入比例等因素会偏好不同的景观。研究表明,运用场景可视化技术将不同利益相关者对村镇体系景观空间格局的偏好融入景观评价中,是一种比较实际、可行的方法。

Rural landscape evaluation is an important basis for rural landscape planning. This article through the scene visualization technolo- gy, using image processing software simulation in the same background different spatial landscape characteristics of agricultural production mode of different gradient and the scenes pictures and through the participatory evaluation technology, getting 180 respondents preferences will of eight villages and one town in Wushi County of Aksu Prefecture, the findings statistics, analysis, evaluation of different stakeholders on rural landscape development tendency preferences. Results show that： generally speaking, most participants would not choose diversity strong land- scape; Most participants prefer fragmentation weaker landscape; The preference for landscape gathered degrees in various interest groups de- gree what the differences are not obvious ; The participants through the scene picture of landscape and garden more preference by language and rational thinking are more inclined to choose after field landscape. Participants for age, their cultural degree, income, income ratio of agricul- tural production factors such as different landscape may prefer. Studies show that, using the scene visualization technology will different stake- holders rural landscape spatial pattern of the preference into landscape evaluation, is a more practical and feasible method.
