【摘要】：海洋傾廢是利用海洋環(huán)境的自凈作用處理廢棄物質(zhì)從而減輕陸地污染程度的有效方法,但與此同時(shí)也引起了海域內(nèi)懸浮泥沙含量的增加,進(jìn)而影響水體的光學(xué)性質(zhì)及近岸海域沖淤變化；沿海地區(qū)經(jīng)濟(jì)的迅速發(fā)展和海洋傾廢活動(dòng)的增加給海洋環(huán)境造成了巨大的壓力,因此對(duì)傾廢區(qū)內(nèi)懸浮泥沙濃度進(jìn)行監(jiān)測(cè)有利于海洋傾廢活動(dòng)的監(jiān)督管理。傳統(tǒng)的懸浮泥沙監(jiān)測(cè)方法耗時(shí)耗力,難以全面、及時(shí)的監(jiān)測(cè)海域內(nèi)懸浮泥沙濃度變化；遙感技術(shù)因大面積同步監(jiān)測(cè)的優(yōu)勢(shì)而被廣泛應(yīng)用,近年,新型的地球同步軌道衛(wèi)星成功發(fā)射運(yùn)行,其高時(shí)間分辨率優(yōu)勢(shì)彌補(bǔ)了極軌衛(wèi)星傳感器重訪周期較長(zhǎng)的缺陷,可追蹤監(jiān)測(cè)傾廢區(qū)海域的懸浮泥沙濃度的連續(xù)變化,進(jìn)而分析傾廢活動(dòng)引起的環(huán)境影響,也可以對(duì)非法傾倒進(jìn)行監(jiān)督管理。本研究以海州灣傾廢區(qū)為例,基于FLAASH模塊對(duì)GOCI影像進(jìn)行大氣校正處理,并根據(jù)現(xiàn)場(chǎng)實(shí)測(cè)光譜和GOCI等效波段遙感反射率之間的相關(guān)關(guān)系建立模型,開(kāi)展懸浮泥沙濃度遙感反演研究；將模型應(yīng)用于傾廢區(qū)海域,對(duì)傾廢區(qū)海域懸浮泥沙濃度的短時(shí)間連續(xù)變化和長(zhǎng)時(shí)間序列變化結(jié)果進(jìn)行綜合分析；結(jié)果表明：基于GOCI第四和第七波段等效遙感反射率比值為遙感因子建立的反演模型精度較高,RMSE為12.06 mg/L, MRE為25.4%,將其應(yīng)用于研究區(qū)域后制作的產(chǎn)品專題圖,可以較好的反映海州灣懸浮泥沙分布及變化狀況,進(jìn)而分析傾廢活動(dòng)對(duì)海域產(chǎn)生的長(zhǎng)、短期影響,綜合GOCI反演結(jié)果可知海州灣內(nèi)航道工程傾廢活動(dòng)的頻繁進(jìn)行引起了海域短期內(nèi)懸浮泥沙濃度的驟增,與周圍背景水體差異較大,但隨著傾廢力度的減小及海域內(nèi)水動(dòng)力作用,使得傾廢區(qū)內(nèi)水體恢復(fù)較好,沒(méi)有對(duì)海洋環(huán)境造成嚴(yán)重影響,也進(jìn)一步證明了GOCI的高時(shí)間分辨率優(yōu)勢(shì)對(duì)海洋傾廢連續(xù)性監(jiān)測(cè)具有重要的意義和作用。
[Abstract]:Ocean dumping is an effective way to reduce the level of land-based pollution by using the self-purification of marine environment to treat waste materials, but at the same time, it also causes the increase of suspended sediment content in the sea area. The rapid economic development of coastal areas and the increase of ocean dumping activities have put great pressure on the marine environment. So the monitoring of suspended sediment concentration in dumping area is beneficial to the supervision and management of ocean dumping activities. Traditional methods of suspended sediment monitoring are time-consuming and labor-consuming, so it is difficult to monitor the variation of suspended sediment concentration in a comprehensive and timely manner. Remote sensing technology has been widely used in recent years because of the advantage of large-scale synchronous monitoring. The successful launch and operation of the new type of geosynchronous orbit satellite has made up for the defects of the revisiting period of the polar orbit satellite sensor due to its high temporal resolution advantage, and it can track and monitor the continuous variation of suspended sediment concentration in the sea area of the dumping area. Furthermore, the environmental impact caused by dumping activities can be analyzed, and illegal dumping can also be supervised and managed. Taking the dumping area of Haizhou Bay as an example, the atmospheric correction of GOCI image is carried out based on FLAASH module, and the model is established according to the correlation between the field measured spectrum and the remote sensing reflectance of GOCI equivalent band. The remote sensing inversion of suspended sediment concentration is carried out, and the model is applied to the sea area of dumping area, and the results of short continuous variation and long time series variation of suspended sediment concentration in dumping area are analyzed synthetically. The results show that the inversion model based on the ratio of the fourth and seventh bands of GOCI, which is a remote sensing factor, has a high accuracy, and a RMSE of 12.06 mg/L, MRE is 25.4. The model is applied to the product thematic map made after the study area. It can better reflect the suspended sediment distribution and variation in Haizhou Bay, and then analyze the long-term and short-term effects of dumping activities on the sea area. The results of GOCI inversion show that the frequent dumping activities in Haizhou Bay waterway cause a sharp increase of suspended sediment concentration in the sea area in a short period of time, which is quite different from the surrounding water body, but with the decrease of the dumping intensity and the hydrodynamic effect in the sea area, It also proves that the high temporal resolution advantage of GOCI is of great significance and function to the continuous monitoring of ocean dumping.
