摘　　要：依据土壤养分、降水量和主要经济作物的平均经济产量对研究区域土壤资源的适宜性和作物土地适宜性进行了初步评价。运且具有 S-型特征函数的 B- P人工神经网络技术 ,从景观生态学的角度 ,以及 3个时期 6种主要斑块类型的面积及其斑块数作为标准训练样本的输入特征 ,建立了面向乡村景观规划的神经网络模型。利用该模型 ,从 9个随机方案中筛选出 3个优化、可行的景观规划方案。在优化方案的实施过程中 。Research on rural landscape planning was conducted at Nanhua Farm,which is located in the south of the Leizhou Peninsula,Guangdong Province.Based on the soil nutrient status,rainfall and mean yield of major crops,the soil suitability and land adaptability were evaluated An artificial neural network was introduced as and alternative for modeling the landscape planning.A model was developed using back propagation as the learning procedure,the sigmoid function as the transfer function and 6 patch types and its number of three phases as input factors. 3 optimum planning schemes were selected by using the model.Strategies were proposed for improving divesity and heterogeneity,productivity and sustainability within the system through the planning scheme.
