| 摘 要： | 结合遥感、地理信息系统、景观生态学和空间分析等理论,分析了新疆地区2000~2015年农业景观格局的时空动态变化特征,测算了农业生态系统服务价值,通过相关分析进一步研究了农业景观格局与生态系统服务价值的关联,为促进区域土地资源合理利用和生态农业发展提供科学依据。结果表明,新疆农业生态系统正朝着多样化、稳定化的方向发展;农业生态系统服务价值显著增长,但区域间的价值差异较大,呈现北疆高南疆低的分布格局;景观面积、斑块数和景观形状对新疆地区农业生态系统服务价值影响较大且均呈现明显正相关关系。

| Abstract: | This study integrated RS, GIS, landscape ecology and spatial analysis, with the aim of analyzing spatiotemporal changes in agricultural landscape patterns, calculating agricultural ecosystem service value (AESV) during 2000-2015 in Xinjiang, China. Through the correlation analysis the relationship between the agricultural landscape pattern changes and AESV was further studied. It provided the scientific basis for the development of ecological agriculture, and promoted the sustainable development of agriculture into the future. Results showed that agricultural ecosystem was moving in the direction of diversification and stabilization. AESV increased significantly, but there were great regional differences of AESV, AESV was higher in the north and lower in the south. Besides, landscape area, patch number and landscape shape index had a significant positive correlation with AESV in Xinjiang. |
