- 摘要:
- 21世纪初的玛纳斯县域土地利用面临新的政策和技术背景，采用遥感技术对2000年和2005年玛纳斯县域人类主要活动区各类景观进行对比分析，发现研究区内耕地、城镇景观面积出现大幅增长，林地、草地景观面积显著下降，“农林”、“农草”争水、争地的矛盾逐渐激化，水资源的供需处于“紧平衡”状态，区域景观生态系统的多样性、稳定性降低。分析表明导致玛纳斯县域景观生态变化的驱动因素主要包括当地气候条件的变化、农业相关政策的推行、农业节水灌溉技术的突破和农业生产合作形式的创新。
- Abstract:
- The use of land in Manas county-region is facing new policy and technical backgournd in the beginning of 21st century.With remote sensing technology,the author compares and analyzes the various landscapes of human-active regions there in 2000 and 2005,points out the great increase of farming land,areas of town landscape,and the dramastic decrease of forest land,grass land.The author also finds that among the farming land,forest land and grass land,the conflicts about water and land have lead to the ‘tense balance’ of water resources,and the diversity and stability of the landscape of eco-environment system in this region has been reduced.This analysis shows there are some impelling factors responsible for this change,such as local climate,related agricultural policy,water-saving cultivated technology and the innovation of agricultural cooperation.
