【摘要】：隨著人類活動(dòng)對生態(tài)系統(tǒng)健康的影響越來越劇烈,生態(tài)系統(tǒng)的健康狀況逐漸引起了人們的重視。流域生態(tài)系統(tǒng)是一個(gè)社會-經(jīng)濟(jì)-自然符合的生態(tài)系統(tǒng),具有一定的完整性；其生態(tài)健康狀況與人類的生產(chǎn)生活密切相關(guān),也引起專家越來越多的關(guān)注。近年來,RS和GIS技術(shù)的日趨成熟為生態(tài)系統(tǒng)健康評價(jià)提供了有力的支撐,采用RS和GIS手段進(jìn)行生態(tài)環(huán)境信息提取和流域生態(tài)健康評價(jià)已被廣泛應(yīng)用。本文以遼河流域?yàn)檠芯繉ο?以遙感數(shù)據(jù)和其他輔助數(shù)據(jù)為基礎(chǔ),結(jié)合水生態(tài)功能三級分區(qū),根據(jù)流域生態(tài)結(jié)構(gòu)將其劃分為水域、岸邊帶、陸域三個(gè)子系統(tǒng),根據(jù)各子生態(tài)系統(tǒng)的特征選取不同的評價(jià)指標(biāo)。水域子系統(tǒng)從水生生境和水生態(tài)脅迫兩方面選取,岸邊帶考慮生態(tài)結(jié)構(gòu)、生態(tài)功能和生態(tài)脅迫三個(gè)方面,陸域子系統(tǒng)關(guān)注生態(tài)格局、生態(tài)功能、生態(tài)脅迫三方面,最終共選取17項(xiàng)生態(tài)健康評價(jià)指標(biāo)。然后,通過層次分析法和專家打分法確定指標(biāo)權(quán)重。以RS和GIS技術(shù)獲取計(jì)算各項(xiàng)指標(biāo),最終采用綜合指數(shù)法對遼河流域生態(tài)健康狀況進(jìn)行評價(jià),揭示遼河流域和各水生態(tài)三級功能分區(qū)的生態(tài)健康綜合狀況。該研究證明,將流域劃分為水域、岸邊帶、陸域分別選取指標(biāo),采用合理的指標(biāo)綜合評價(jià)方法,以遙感和GIS技術(shù)結(jié)合為核心,開展流域生態(tài)系統(tǒng)健康綜合評價(jià)研究是可行的,其評價(jià)結(jié)論可以分析和表達(dá)流域生態(tài)系統(tǒng)健康的空間特性,給政策管理者和決策者提供流域生態(tài)建設(shè)的科學(xué)依據(jù),對于流域的生態(tài)保護(hù)和管理起到了重要的作用。
[Abstract]:With the increasing influence of human activities on ecosystem health, people pay more and more attention to ecosystem health. Watershed ecosystem is a social-economy-natural ecological system with certain integrity, and its ecological health is closely related to human production and life, and has attracted more and more attention of experts. In recent years, the maturity of RS and GIS technology has provided strong support for ecosystem health assessment. RS and GIS methods have been widely used to extract ecological environment information and assess watershed ecological health. Based on remote sensing data and other auxiliary data, this paper divides Liaohe River Basin into three subsystems according to its ecological structure: water area, shore zone and land area. Different evaluation indexes were selected according to the characteristics of each sub-ecosystem. The water area subsystem is selected from two aspects of aquatic habitat and water ecological stress. The coastal zone considers ecological structure, ecological function and ecological stress. Land subsystem pays attention to ecological pattern, ecological function and ecological stress. Finally, a total of 17 ecological health evaluation indicators were selected. Then, through the Analytic hierarchy process and the expert scoring method to determine the index weight. The indexes were obtained by RS and GIS techniques, and the comprehensive index method was used to evaluate the ecological health status of Liaohe River Basin, and to reveal the ecological health comprehensive status of Liaohe River Basin and the three functional zones of water ecology. The research proves that it is feasible to divide the watershed into water area, shore zone and land area, select the index separately, adopt reasonable index comprehensive evaluation method, take remote sensing and GIS technology as the core, and carry out the comprehensive evaluation research of watershed ecosystem health. The evaluation results can analyze and express the spatial characteristics of watershed ecosystem health, provide scientific basis for policy managers and decision makers, and play an important role in watershed ecological protection and management.
