| 摘要: |
| 在土地生态规划设计原则和方法的基础上，以陕西淳化县西坡村为例，利用生态学、经济学、景观生态学以及系统工程学的理论，借助于GIS技术，对其土地生态系统进行了分析。结果表明，坡度和土壤性质是影响土地生态特征的两个主要因子，故依据地貌垂直分异特征、坡度和土地生产力指数（PI）将全村39个土地生态单元归并为7大类，并按地貌、坡度、土壤3个生态特征因子，对各土地生态类型的利用进行了适宜性评价，然后利用交互式线性规划软件（LINDO）对全村土地利用进行了生态规划，最后作出不同土地生态类型利用的设计。 |

| Abstract: |
| Based on the principles and methods of eco-land planning and designing and GIS with the Xipo village of Chunhua country as an example,the eco-land planning and designing was analyzed with theories of ecology,economics,landscape ecology and systems engineering.The results show that gradient and soil are the two main factors influencing the land ecological characteristics.So according to vertical differentiation characteristic of the physiognomy,gradient and land productivity index (PI),the 39 land ecological cells in Xipo village was classified into 7 different eco-land types.And by three ecological characteristic factors of physiognomy,gradient and soil,were the use suitability of every eco-land type evaluated and the eco-planning for the whole land use was made by LINDO.Finally,on the basis of classifying different eco-land types and making eco-planning,the paper put forward the superior pattern of eco-designing for different land types. |
