溶解性无机碳(DIc)%DIC与T、pH%DO的相关性
溶解性無機碳(DIc)%DIC與T、pH%DO的相關性
용해성무궤탄(DIc)%DIC여T、pH%DO적상관성
the dissolved inorganic carbon(DIC)%the correlation with DIC and pH%DO,T
水体中溶解性无机碳（DIc）为无机碳酸盐，碳酸氢盐、碳酸及二氧化碳气体的总和，是水生植物特别是沉水植物在进行光合作用时的主要碳源，因此研究水体中溶解性无机碳的变化行为，有助于从碳源利用的角度合理确定水生生态系统中沉水植物的种植密度。本项日首先提出浴解性无机碳的简易测定方法并进行了可行性论证，并在良好的水生生态系统中研究：DIC与温度（T）、pH、溶解氧（DO）的短期和长期相关性。研究结果表明：本法所采用的DIC简易测定方法是可信的：DIC在短期内与pH、DO、T负相关；长期则呈正相关且受温度控制。
水體中溶解性無機碳（DIc）為無機碳痠鹽，碳痠氫鹽、碳痠及二氧化碳氣體的總和，是水生植物特彆是沉水植物在進行光閤作用時的主要碳源，因此研究水體中溶解性無機碳的變化行為，有助于從碳源利用的角度閤理確定水生生態繫統中沉水植物的種植密度。本項日首先提齣浴解性無機碳的簡易測定方法併進行瞭可行性論證，併在良好的水生生態繫統中研究：DIC與溫度（T）、pH、溶解氧（DO）的短期和長期相關性。研究結果錶明：本法所採用的DIC簡易測定方法是可信的：DIC在短期內與pH、DO、T負相關；長期則呈正相關且受溫度控製。

The dissolved inorganic carbon in water（DIC） were conducted by carbonate, bicarbonate, carbonic acid and carbon dioxide. DIC is the main carbon source for photosynthesis of aquatic plant especially for benthophyte, so the research is helpful to plant the density of submerged aquatic plants in aquatic ecosystems. We researched the measuring method of dissolved inorganic carbon in water and then proved its feasibility, at the same time, we researched the correlation with DIC and pH, DO, T in short-term and long-term in the aquatic ecosystem. The study showed that, the simple measuring tnethod used in the research was believable, the DIC changing trends was negative correlation with pH, DO, T in Short-term, but in long-term, the correlation was positive and the concentration of D1C was controlled by T.
