【摘要】：河流水系連通性具有水文調(diào)蓄、保障生物遷徙通暢、改善水土環(huán)境等功能,目前主要從水文、景觀和生態(tài)等方面對其進(jìn)行了定義,而河流水系連通性對社會(huì)發(fā)展也發(fā)揮著重要作用,故河流水系連通性具有自然和社會(huì)雙重屬性,其連通性機(jī)制主要表現(xiàn)為縱向、橫向、垂向連通性。目前主要從景觀學(xué)、水文學(xué)、水力學(xué)、生態(tài)學(xué)等學(xué)科角度提出了圖論法、水文-水力學(xué)法、景觀法、生物法和綜合指標(biāo)法等計(jì)算方法,各方法有其適用性和不足,應(yīng)用中須針對實(shí)際問題選擇適宜方法或進(jìn)行修正。河流水系連通性未來研究應(yīng)綜合多尺度、多領(lǐng)域、多學(xué)科,在研究內(nèi)容上,重點(diǎn)開展尺度協(xié)同、連通性含義界定、響應(yīng)機(jī)理及修復(fù)問題研究,在研究手段上,重點(diǎn)開展多方法、多技術(shù)集成問題研究。
[Abstract]:The connectivity of river system has the functions of regulating hydrology, ensuring the smooth migration of living things and improving the soil and water environment. At present, it is mainly defined from the aspects of hydrology, landscape and ecology. The connectivity of river system also plays an important role in social development, so the connectivity of river system has both natural and social attributes, and its connectivity mechanism is mainly vertical, horizontal and vertical connectivity. At present, from the angle of landscape science, hydrology, hydraulics and ecology, this paper puts forward some calculation methods, such as graph theory method, hydrology method, landscape method, biological method and comprehensive index method. In application, it is necessary to select appropriate methods or to correct them in view of practical problems. The future research on river system connectivity should integrate multi-scale, multi-domain, multi-disciplinary, and focus on scale synergy, definition of connectivity meaning, response mechanism and repair problems, and multi-methods in research means. Research on multi-technology integration.
