Land-use change and its response analysis has important practical significance to the sustainable development of the region. Based on the data of land use in 2005 and 2012 ,by constructing the Markov model and ecosystem service value table , its combined with the related general land use planning, and carries out dynamic simulation and prediction on the landscape pattern of Zhangjiagang and its ecosystem service value from 2019-2026. The results showed that between 2005-2012, changes in land use types plaque area of 9996.12hm2, arable land and waters appear relatively substantially reduced, main transfer for towns and construction land and garden plot; According to the current Temporal and Spatial Trends, 2019-2026, the construction area will continue to increase, water and arable land continues to decline. Leading to its ecological response is negative, and ecosystem service value reduced year by year, the rate is 11.5557 million yuan / a, including food production, gas regulation, climate regulation, hydrology regulation, maintain biodiversity and waste treatment significantly reduce, it may lead to the problem such as environmental deterioration, biodiversity loss in the study area. The government should take timely measures to strengthen the protection of arable land and water area, reduce the construction land expansion rate, change the present trend of land use change, keep the ecosystem health.
