中文摘要：
从土地生态学的角度探讨景观生态质量的评价理论和方法。景观生态质量（LsEQ）是景观生态系统维持自身结构与功能稳定性的能力，因此，景观生态质量的衡量标准是景观生态系统的稳定性，其稳定性取决于景观生态系统的自身稳定程度与外部生态学干扰程度的对比。以吴江市为例进行实证研究，结果表明，吴江市景观生态质量等级呈西南高、东北低的空间分布态势，评价结果与实际情况吻合，表明该评价方法有一定可行性。
英文摘要：
This paper discussed the evaluation theory and method of landscape ecological quality （LsEQ） from angle of land ecology. LsEQ is the ability of landscape eco-system to maintain self-stability of structure and function. So, assessment standard of LsEQ is defined to be the stability of landscape eco-system which lies on the contrast of interior stabilization degree and exterior ecological disturbance degree of landscape eco-system. In this paper, demonstration study has been made in Wujiang County. Evaluation result showed that, grades of LsEQ of Wujiang County show the sequence for different space locations in the following order： southwest 〉 northeast. Evaluations result accorded with the fact and showed that this evaluation method has some feasibility. Research on evaluation of LsEQ has important meaning to land ecological management and sustainable land use.
