摘要:
生态系统功能是指生态系统与生态过程所形成及所维持的人类赖以生存的自然环境条件与效用，与人类的生产生活密切相关。以RS和GIS技术为基础，利用TM遥感影像、植被NDVI以及气象等数据，计算2000—2010年辽河流域土地利用、景观格局、植被覆盖、水源涵养能力、土壤侵蚀强度以及生物多样性保护能力等指标的变化，从而分析近10 a来辽河流域生态系统基本状况以及变化趋势。结果表明：近10 a间，辽河流域城镇在一定程度上有所扩张，但并未破坏生态用地；植被覆盖度、水源涵养能力、生物多样性保护能力都有提高；土壤侵蚀强度有所增加，一定程度受2010年降水量的影响。总体来说，2000—2010年，辽河流域生态系统功能基本处于稳定且有转好的的趋势；但仍需注意城镇的扩张对耕地以及生态用地的影响。
Abstract:
Ecosystem functions refer to the natural environmental conditions and effectiveness for human survival and utility conditions, and are closely related to the life and production of human. Based on RS and GIS technology, using TM remote sensing images, NDVI of vegetation and meteorological data, change of land use types, landscape pattern, vegetation coverage, water conservation, soil erosion and biodiversity conservation were calculated in order to analyze the basic status and change trend of ecosystem functions in Liao River basin in the last decade. The results showed that in recent 10 years, the urban area expanded in the study area, but had little damage to ecological land; vegetation coverage, ability of water conservation and biodiversity conservation enhanced; while soil erosion exacerbated due to the rise in precipitation to some extent. Overall, ecosystem functions in Liao River basin were basically stable and had a better trend; but impaction on arable land and ecological land from urban expansion should be noticed.
