| 中文摘要 | 本文选取米易县和双流县作为山区与平原的典型区域，利用1986、1995和2000年的三年同期陆地卫星的TM影像作为主要数据源，经过人工解译生成土地分类数据，采用ArcGIS的空间分析功能和相关数学分析模型，对两个县的土地利用/覆被格局特征、土地利用的动态变化进行了分析，并据此对区域土地可持续利用提出建议。 研究结果： 1.采用ArcGIS的空间分析功能对区域土地利用/覆被变化进行分析是可行的，能更为深入和准确地认识区域土地利用的动态演变过程和变化程度。 2.山区的土地利用类型明显多于平原地区(米易县有23种二级土地利用类型，双流县只有16种)。1986～2000年两个地区的土地利用/覆被的空间格局并未出现明显的变化，但其土地利用结构却表现出明显的差异。米易县主要以林地和草地等自然景观为主，而双流县则以耕地和建设用地为主，表现出很明显的人类活动属性。 3.斑块特征 总体上，米易县斑块的平均周长与平均面积都大于双流县，双流县的总体斑块复杂性与破碎度要比米易县大，景观受到的干扰程度比较大。 在自然景观(林地、草地与水域)上，米易县的斑块特征表现出的是单个斑块(平均面积)大而(斑块数)多，空间分布比较连续，而双流县则表现出小、少，散、碎的特征；在人为景观(建设用地与耕地)上则相反，双流县的斑块特征相对于米易县表现出大而多，空间分布比较连续。 4.土地利用/覆被变化 ①时空分布上，米易县变化区域显得比较分散，而双流县则比较集中，与人口，经济分布的空间分布较一致。 ②单一土地利用/覆被动态变化上，米易县的单一土地利用类型的动态变化较活跃的是林地、草地、耕地与水域，而双流县则主要集中在耕地与建设用地。 ③从转移与来源构成上看，米易县土地利用类型的转移方向与来源构成表现得比较平衡，各种土地利用类型之间的转换都占有一定的比例，土地利用类型之间的转移变化比较复杂。而双流县土地利用变化强烈地表现为耕地大量的流向建设用地。 ④从土地利用的综合程度上看，双流县的综合土地利用程度远高于米易县；米易县整体还处于土地利用结构优化、调整阶段，双流县则处于发展阶段。 5.土地可持续利用 根据米易县与双流县的土地利用/覆被变化的特点，提出区域土地可持续利用的建议。即：适度保护农地资源尤其是耕地资源，合理协调农业用地与非农业用地之间的相互关系；要根据区域的自然环境与经济发展等实际特点对土地利用进行科学合理的发展规划，在土地利用的某些政策上要对山区与平原之间实施差别化对待。 |
| 英文摘要 | This paper selected Miyi County and Shuangliu County as the typical area of Mountain Area and Plain Area. The land use/cover classification was built by manually interpreting the main data which were based on the Landsat TM image over the same period in 1986,1995 and 2000 as the main data source．Then the overall characteristics of 1and use/cover pattern, the changed of the 1and use/cover will be also analyzed by using the spatial analysis of ArcGIS and related mathematical functions model in the study area．Finally some suggestions are put forward to advance the research of sustainable land use. It is showed that: 1. Its feasible that used the ArcGis spatial analysis model to analyze the LUCC in the study area. The proposed spatial analysis model can figure out the spatial changes of land use and quantitative analysis, and more precisely measure the dynamic change rate and degree of land use． 2. The land-use types of mountain area were much more than those of the plain area. There were no significant change had taken place in land use/cover of the two areas from 1986 to 2000, but the two areas were extremely different in land use structure. Miyi County was mainly in natural landscape, and the Shuangliu County was mainly in cultivated land and construction land, showed obviously characters of human activity. 3. Patch Characteristics Overall, Miyi County was higher than Shuangliu County in both of the average patch perimeter and the average area. And generally, Shuangliu was larger than Miyi in patch complexity and fragmentation, the landscape more susceptible to interference. Overall, the average meter prone patch perimeter and area are more than double the average, double the overall plaque complexity and fragmentation larger than rice, the extent of the landscape more susceptible to interference. At the natural landscape (woodland, grassland and waters), the single patch of Miyi County showed that its number was many and its area was large, spatial distribution were more continuous and homogeneous, and Shuangliu County showed small, little, fragmented, dispersed. At the artificial landscape (construction land and cultivate land) showed inverse situation. 4. Land Use / Cover Change ① Spatial and temporal distribution on land use / cover change. The changed areas in Miyi County were more decentralized, and Shuangliu is more concentrated, congsistant with the population and economic of the spatial distribution. ② Single land use / cover dynamics change. The active land use / cover types of dynamics change in Miyi were woodland, grassland, cultivate land and waters, and Shuangliu was mainly in the cultivate land and construction land. ③ Constitute of transfer and source. The consistant of transfer and sourse in Miyi had a balanced showed and complex, every types of land use had a proportion between all of conversions. And Shuangliu showed strongly of the cultivate land confer to construction. ④ General extent of land-use integrated. Shuangliu was much higher than Miyi in general extent of land-use. Miyi was still at the adjustment and optimization in land use structure, and Shuangliu at development period. 5. Susatinable landuse Finally some suggestions are put forward to advance the research of sustainable land use. that is，properly protecting agricultural land resource especially cultivated land, reasonably harmonizing the relationship between agricultural land and non-agricultural land; It should be in accordance with the regional natural environment and economic development to carry out a scientific and rational land use planning, some of the land-use policy should be differentiation treated between the mountain area and plain area. |
