通过野外调查、航片解译和农户调查 ,应用地理信息系统 ,对不同时期 ( 1 95 5、1 977、1 984、1 993)亚热带江汉平原农业景观格局变化以及与社会经济变革和农作系统多样性的相互关系、不同类型景观单元的生物多样性 ,进行了案例研究。指出 ,景观格局变化受大尺度因素和小尺度因素相互作用影响 ;庭院中树篱和林地以及农田边界可能是保持生物多样性最重要的景观单元 ,稳定这些景观单元可能是景观生态及农作系统持续性管理最重的组成部分。
Through the field survey, the interpretation of aerial photos and the survey of farmers, the application of geographic information system (GIS) was used to analyze the changes of agricultural landscape pattern in the subtropical Jianghan Plain in different periods (1 95 5,1 977,1 984,1 993), and the relationship between social and economic change and farming system The interrelationship of diversity and the biodiversity of different types of landscape units, a case study was conducted. It is pointed out that the change of landscape pattern is affected by the interaction of large-scale factors and small-scale factors; the hedgerows and woodlands in the courtyard and the border of farmlands may be the most important landscape units to maintain biodiversity. Stabilizing these landscape units may be the result of the continuous development of landscape ecology and farming systems The most important part of sexual management.
