农业科技园区用地适宜性评价和规划方案评估是规划区用地功能配置的前提。该文以南京农业大学白马教学科研基地为例，应用GIS地形数据和RS遥感数据，在已有用地适宜性模型的基础上，将水生态安全因子融入农业科技园区建设用地适宜性评价指标体系，结合高程、坡度、噪声和土地利用等评价因子，构建功能用地适宜性空间定量模型，阐述了功能用地适宜性评价在规划方案评估中的应用与技术路线，分别对生活功能、公共服务、农业实践、展示功能和教学实践等功能用地适宜性进行定量评价，最后对6种不同规划方案综合用地适宜性进行总体评估，并充分结合空间布局中规划理性要求，确定方案6为最佳规划方案。分析和评价结果显示，结合水生态安全因子对功能用地适宜性进行评价，能够较好地对不同规划方案综合评估，从而选取最佳规划方案，最后为用地功能布局进行辅助决策，因此评价结果具有一定的科学性和实用性。该文将区位选择与农业科技园区规划中的功能布局进行关联，结果表明该文提出的方法是科学可行的，为农业科技园区规划方案评估探索了一种途径，也为城乡用地统筹规划管理提供了科学依据和决策支持手段。

Along with the promotion of urban-rural integration, agricultural scientific parks calls for spatial integrative distributions of functions such as agricultural production services, scientific research, exhibition, science popularize training and tourism. Evaluation of land sustainability classifies sustainability of functions including production, living, relaxing, and ecological security, projects development potential of land with a certain function by current situation, and thus contributes to optimal allocation and rational distribution of land. This study takes an example of Baima Teaching and Research Base of Nanjing Agricultural University with GIS and RS data based on existing models, incorporating water ecological security factors as well as factors such as elevation, slope, noise and land-use into land sustainability evaluation. By quantitative spatial modeling and evaluation, we can give an integrative evaluation of land sustainability of different planning and determines the Plan Six as the best planning. Specific steps are as follows: 1) Determine natural and environmental factors as the main factor impacting the function layout, such as living function, public services, agricultural production, exhibition function and teaching function; 2) Roads and land use data can be obtained through the vectorization of remote sensing data, and then create DEM data through terrain data, thus generated slope combined with ArcGIS terrain analysis on the one hand; get collection waterline according hydrological model on the other hand; 3) Computing the weight value of five kinds of factors of five function layout by combining Analytic Hierarchy Process and expert opinion; 4) Mapping the land suitability of different function layout through overlay analysis by ArcGIS, then analyzing the distribution; 5) According to the results of land suitability analysis, weighted evaluation the total land suitability of different planning scheme, then determines the Plan Six as the highest land suitability; 6) Finally, taking the environmental pollution of agricultural production into account, Plan Six isolated the agricultural production area and living function area; and secondly; Plan Six fully consider the effect of ecological and water landscape of Hanziba Reservoir in the eastern part of the study area, so that the layout of teaching, living and public facilities can make full use of the original soil and water natural resources. Based on the analysis above, determining the Plan Six as the best planning and put it into effect. The conclusions are withdrawn as follow: 1) By incorporating indicators of ecological security pattern of small watershed into the evaluation indicator system, the evaluation of land sustainability become more scientific. 2) Compared with traditional fixed planning scheme in college plans, our model evaluated Six Planning Schemes based on land sustainability. Alternatives analysis and quantitative study combined to reach a more reasonable and applicable spatial distribution scheme. 3) This article integrated the rational requirements of spatial distribution into planning evaluation, thus laid a foundation for qualitative and quantitative modeling of agricultural teaching and research bases. Scientific and practicability of evaluation results can be concluded as results show that land sustainability evaluation with water ecological security makes an effective evaluation and comparison of different planning for the determination of the best planning and the functional distribution of land. This study demonstrated the feasibility of our method, offered a new approach for the evaluation of agricultural scientific park planning and provided basis and decision support for comprehensive urban-rural land planning.
