【摘要】：構(gòu)建生態(tài)安全格局,對(duì)貫徹保護(hù)優(yōu)先的指導(dǎo)思想具有重要意義。水安全格局作為構(gòu)成生態(tài)安全格局的重要格局,對(duì)保障水生態(tài)系統(tǒng)服務(wù)功能,維護(hù)水安全具有重要意義,對(duì)生態(tài)安全格局中其他安全格局的構(gòu)建具有指導(dǎo)意義。在此背景下,本文在研究生態(tài)安全格局構(gòu)建理論與方法的基礎(chǔ)上,以阿城區(qū)為研究對(duì)象,以構(gòu)建阿城區(qū)水安全格局為目的,針對(duì)阿城區(qū)現(xiàn)有水安全問題構(gòu)建水安全評(píng)價(jià)體系,并在評(píng)價(jià)結(jié)果的基礎(chǔ)上提出阿城區(qū)水安全格局規(guī)劃導(dǎo)則。本文在對(duì)阿城區(qū)現(xiàn)有水安全現(xiàn)狀分析的基礎(chǔ)上,基于雨洪災(zāi)害風(fēng)險(xiǎn)性評(píng)價(jià)、水質(zhì)敏感性評(píng)價(jià)與水生境適宜性評(píng)價(jià)的相關(guān)理論研究對(duì)評(píng)價(jià)指標(biāo)進(jìn)行選取;在DPSIR評(píng)價(jià)模型的基礎(chǔ)上建立水安全評(píng)價(jià)體系;運(yùn)用專家打分法與AHP評(píng)價(jià)法,從雨洪、水質(zhì)與水生境三個(gè)方面運(yùn)用Arc GIS技術(shù)對(duì)阿城區(qū)水安全進(jìn)行評(píng)價(jià),并疊加得到綜合水安全評(píng)價(jià)結(jié)果。通過研究,本文根據(jù)評(píng)價(jià)結(jié)果,從宏觀到微觀,分別以達(dá)到阿城區(qū)雨洪安全、水質(zhì)安全與水生境安全為目標(biāo)提出規(guī)劃導(dǎo)則,并分別以流域尺度的單一安全格局為上位條件,給出了河流廊道規(guī)劃導(dǎo)則與起到關(guān)鍵作用的濕地規(guī)劃措施。并針對(duì)單一安全格局疊加形成的綜合水安全格局,從流域尺度與河流廊道尺度提出規(guī)劃導(dǎo)則。本文旨在從防洪排澇與生態(tài)保護(hù)與發(fā)展的角度去構(gòu)建科學(xué)合理的水安全格局并提出規(guī)劃導(dǎo)則,以達(dá)到保護(hù)、維護(hù)、保障及恢復(fù)水生態(tài)系統(tǒng)服務(wù)功能的目的。
[Abstract]:The construction of ecological security pattern is of great significance to the implementation of the guiding ideology of priority protection. As an important pattern that constitutes ecological security pattern, water security pattern is of great significance to ensure the service function of water ecosystem and maintain water safety. It is of guiding significance for the construction of other security patterns in the ecological security pattern. Under this background, based on the study of the theory and method of constructing the ecological security pattern, this paper takes Acheng District as the research object. In order to construct the water safety pattern in Acheng District, the water safety evaluation system is constructed for the existing water safety problems in Acheng District. Based on the evaluation results, the planning guidelines for water safety patterns in Acheng District are put forward. Based on the analysis of the present situation of water security in Acheng District, the risk assessment of rainwater and flood disasters is carried out in this paper. Theoretical study on sensitivity Assessment of Water quality and suitability of Water Habitat; on the basis of DPSIR evaluation model, water safety evaluation system was established; expert scoring method and AHP evaluation method were used to evaluate water quality; Three aspects of water quality and water habitat are used to evaluate the water safety of Acheng district by Arc GIS technique, and the results of comprehensive water safety evaluation are obtained by superposition. According to the evaluation results, the paper achieves rain and flood safety in Acheng district from macro to micro, respectively. Planning guidelines for water quality safety and water habitat safety are put forward, and the single security pattern on watershed scale is taken as the upper condition respectively. The guidelines for river corridor planning and the key wetland planning measures are given, and the comprehensive water security pattern formed by the superposition of a single safety pattern is presented. The purpose of this paper is to construct a scientific and reasonable water security pattern from the point of view of flood control, drainage and ecological protection and development, and to put forward planning guidelines to achieve protection and maintenance. The purpose of protecting and restoring the service function of water ecosystem.
