Wulan Delta is a form of landscape in the coastal area of Wedung District, Demak Regency, which was formed due to sedimentation of the Wulan River estuary. Utilization of the delta region into a pond will have an impact on the environment and socio-economic surrounding communities. This study aims to look at the dynamics of land cover changes in Wulan Delta, Wedung District, Demak Regency. Multitemporal remote sensing technology can be used to see the dynamics that occur in the Wulan Delta region. Remote sensing imagery used by Quickbird imagery from 2003 and Worldview imagery from 2017. Based on the results of the interpretation of multitemporal imagery that most of the Wulan delta area is used as ponds. Along with the increase in the pond area, from the socio-economic aspects of the livelihoods of residents in the sub-district of Wedung as pond farmers increased from 2003 to 2017. So that the use of land in the form of ponds has a positive impact as the livelihood of the population. Changes in the area of Wulan Delta between 2003 and 2017 there are delta gain as large as 112,9 ha (7,9 %), delta loss area by 28,78 ha ((2,01 %) and a fixed area of 1287,77 ha (90,09%). Delta area changes also affect land cover changes from mangroves into ponds 29,73 ha (2,08%) and pond to mangrove 8,81 ha (0,62%). The land cover dynamics changes of Wulan Delta also affect the socio-economic conditions of surrounding communities, most of whom work as pond farmer. Calculation of the production value of ponds in the study area is estimated at approximately IDR 39.422.252.670,-.

乌兰三角洲是德马克摄政区韦东区沿海地区的一种景观形式，因乌兰河口的沉积作用而形成。将三角洲地区利用成池塘将对环境和周边社区的社会经济产生影响。本研究旨在研究德马克摄政区韦东区乌兰三角洲土地覆盖变化的动态。多时相遥感技术可用于观察乌兰三角洲地区发生的动态。2003 年 Quickbird 影像和 2017 年 Worldview 影像使用的遥感影像。根据多时相影像解释结果，乌兰三角洲大部分地区被用作池塘。随着池塘面积的增加，从社会经济方面来看，2003 年至 2017 年，Wedung 街道居民作为池塘养殖者的生计有所增加。因此，以池塘形式使用土地对居民的生计产生了积极影响。乌兰三角洲 2003 年至 2017 年的面积变化，三角洲增加了 112.9 公顷（7.9%），三角洲损失面积增加了 28.78 公顷（（2.01%），固定面积为 1287 ,77 公顷 (90,09%)。三角洲面积变化也影响土地覆盖变化，从红树林到池塘 29,73 公顷 (2,08%) 和池塘到红树林 8,81 公顷 (0,62%)。土地覆盖乌兰三角洲的动态变化也影响了周边社区的社会经济状况，其中大部分是池塘养殖者。计算研究区池塘的产值估计约为 IDR 39.422.252.670,-。
