摘要：Urban green space are significant elements of the city, which brings us many free ecological products and benefits, such as absorbing CO2, releasing oxygen, releasing negative air ion, foliar dust-retention and so on. However, with the rapid development of urban-rural integration, to a certain extent, urban green space are threatened and destroyed by human factors, which leads tofragmentation of landscape pattern and area of reduction, seriously affects its eco-service function. This paper, taking Beidaihe district as an example, analyzed the dynamic change of landscape patterns based on the remote sensing image of 2002, 2007, 2012 and 2017, quantitatively evaluated the eco-service value of urban green space, discussed the mutual influence between them. The results are as follows: (1) Urban green space gradually increased before 2007, and then gradually decreased trend. Farmland has been seriously occupied over the past 15 years, with a decrease of 46.61% and construction increased by 41.54%. Patches at landscape level showed fragmentation, construction and urban green space had become the dominant landscape of Beidaihe. (2) The total eco-service value of urban green space had been increasing year by year, reaching a maximum of 14.487.63 million yuan/a in 2017, the rank of evaluation indicators were forest recreation (40.98%) > releasing oxygen (23.18%) > abating noise (14.45%) > absorbing CO2 (10.29%) >lower temperature (6.45%) > foliar dust-retention (4.48%) > releasing NAI (0.17%). (3) Forest recreation value had a high relevance degree with NP and PD; SHDI, Contag and AI had a high relevance degree with single and total eco-service value; the relevance degree between construction land and ecoservice value was low. The results evaluate objectively the interaction mechanism between landscape pattern indexes and eco-service value in the study region and provide a reference for landscape construction of urban and protection of urban green space.
