【摘要】 城市是社会生产力发展的必然产物，城市化程度是一个国家或地区经济发展水平的重要标志之一。随着城市化浪潮的到来，我国中等城市迈进了机遇与挑战并存的高速发展时期，同时也面临着快速城市化带来的环境污染、交通拥挤、住房紧张等一系列问题。如何创造良好的人居环境，建设高效的城市形态，探求健康的中等城市发展模式，成为当前城市发展过程中探讨的热点。城市景观生态学应用景观生态学原理和方法，研究城市景观格局、功能及其过程、动态等，其原理和规律为城市景观规划设计、经营管理提供了理论基础，为城市发展战略提供了科学的依据及解决城市问题的新途径。 资阳市雁江区是四川盆地腹心一个典型中等丘陵城市。近年来随着城市化进程的加快，城市规模迅速扩长。老城区原有不合理布局限制了城市生态系统的有效运行，因而旧城改造、新区建设需要科学的景观布局优化方案，为城市可持续发展提供导向。本研究以资阳市雁江区为实例，结合景观生态学与地理信息系统基本理论和研究手段，探讨城市景观生态学在解决中等城市快速城市化进程中城市景观格局不合理与城市可持续发展之间的矛盾，寻求景观格局优化的新思路。 通过景观斑块属性等方面的分析，本文将资阳市雁江区中心城区城市景观划分为四类一级景观，即建设景观、环境景观、水体景观、特殊景观；九更多还原

【Abstract】 Urbanization is an inevitable consequence of social productivity development, and the urbanization level is also one of the embodiments of economy development in one country or region. However, fast urbanization brings about a series of problems, such as environment pollution, traffic block and housing shortage. Therefore, how to construct a well-designed sustainable urban with high efficiency and high-quality environment is becoming one of the hot topics for landscape ecologists worldwide. Urban landscape ecology provides urban landscape planning, design and management with the theoretical foundations through implementing the theories and methodologies of landscape ecology. In Addition, some new ways and scientific proof are provided to solve urban issues for urbanization strategies.Ziyang is a typical mid-scale city in hilly region of Sichuan Basin, and now it is experiencing a fast urban expansion as other cities in China. The distribution of old city limits the city’s further development. Hence, the flourishing development of the city requires well-designed optimization program for urban landscape. Based on the principles of landscape ecology and GIS, new methods for solving the problems of expansion and conflicts between unreasonable landscape pattern and city’s sustainable development were discussed in this paper.更多还原
