Preliminary researches on the functional evaluation of rural landscape

The general purposes of integrated rural landscape evaluation are to appropriately assess social, economic, ecological, and aesthetic functions of rural landscapes, to identify problems that might exist in the present state, to point out potential directions of future development, and to provide bases for optimal planning and designing of rural landscapes. In this paper, the meaning of functional evaluation of rural landscape was probed. On the basis of three functions of rural landscape, an index system including item, factor and index was constructed. Based on this,the model of integrative evaluation was constructed, and applied to nine towns in Shunyi district, Beijing City. The following results were obtained: (1) The social function of landscape in LongWanTun town and MuLin town is relatively low. So it is necessary to establish agricultural science park, to realize structural readjustment and optimization of regional agriculture, and to improve the ratio of transforming agricultural product into commodities and supplies and requirement of agricultural product in LongWanTun town and MuLin town. (2) The ecological function of landscape in LiQiao town and NanCai town is relatively low.When planning and designing landscape in LiQiao town and NanCai town, we should especially pay attention to design functional combination, to conserve natural landscape components such as orchard, woodland, cropland and water area. , so that the ecological stability landscape in LiQiao town and NanCai town can be improved. (3)The aesthetic function of landscape in LiQiao town and NanCai town is relatively low. Designers should pay attention to protect environment and link new architecture to old architecture, and improve greenness coverage. (4) The final evaluation results for evaluation in ZhangZhen town, BeiWu town GaoLiYing town were “better”. those for BeiXiaoYing town,LiQiao town,MuLin town and ZhaoQuanYing town were “ordinary”, and those for NanCai town, LongWanTun town were “worse”. The results are basically consistent with facts of nine towns,so the index system and model of evaluation are justified.
