【摘要】：基于對(duì)洪河濕地退化的影響因素分析,采用層次分析法確定評(píng)價(jià)指標(biāo)及各指標(biāo)權(quán)重,進(jìn)而用綜合指標(biāo)法對(duì)洪河濕地退化進(jìn)行評(píng)價(jià)和退化分級(jí)。結(jié)果表明:洪河濕地退化的影響因素包括氣溫、大氣降水量、濕地水質(zhì)、濕地水量、水利工程建設(shè)和農(nóng)場(chǎng)建造,其中水利工程建設(shè)與農(nóng)場(chǎng)建造所占權(quán)重最大,分別為0.239與0.339;2014年洪河濕地周邊各農(nóng)場(chǎng)退化等級(jí)均為Ⅳ級(jí),退化程度高,處于重度退化且有向極度退化發(fā)展的趨勢(shì);同年,洪河濕地保護(hù)區(qū)內(nèi)綜合評(píng)價(jià)指數(shù)降至0.811退化等級(jí)降為Ⅱ級(jí),為輕度退化。為減緩濕地退化速率,應(yīng)杜絕洪河濕地內(nèi)耕地及排干渠擴(kuò)建。
[Abstract]:Based on the analysis of the influencing factors of the degradation of Honghe wetland, the evaluation index and the weight of each index are determined by AHP, and then the degradation of Honghe wetland is evaluated and classified by comprehensive index method. The results show that the factors influencing the degradation of Honghe wetland include temperature, atmospheric precipitation, wetland water quality, wetland water quantity, water conservancy project construction and farm construction, among which water conservancy engineering construction and farm construction are the most important factors. In 2014, all the farms around Honghe Wetland were grade 鈪，
