Abstract Mountainous rural areas are vulnerable to inappropriate land management, which is particularly visible in the Polish Carpathians. This paper attempts diagnose causes and effects of spatial chaos this area, using DPSIR method. The Three Questions method was used assist analysing disorder context violating sustainable development. analysis demonstrated that were mainly legal historical o...
Under the background of double circulation, national logistics hub will play an important role node, and platform in network. As a strategy, integration Yangtze River Delta matters lot to This study constructs evaluation index system hubs studies construction central China based on DPSIR theory. model integrates advantages pressure-state-response (PSR) driving-state-response (DSR) model, evalua...
From an environmentally conscious and ecological perspective, the sustainability of cities within effects climate change are closely related to wise use resources modifications in status environment. In terms environment, smart entails meeting present future societal demands for environment water, land, air, among others. Environmental concerns that arise from rapid monetary developments shown ...
آلودگی هوا از معضلات اصلی کلانشهرهایی مانند تهران است و کاهش آن به سطح قابل قبول به مسئلۀ بسیار مهم زیستمحیطی در این شهر تبدیل شده است. با توجه به پیچیدگی و تعدد عوامل دخیل در آلودگی هوای تهران، برای شناسایی و مدیریت بهتر این عوامل به روشهای همهجانبهنگر نیاز است. استفاده از مدلهای علی- معلولی از روشهای چندبعدی و سیستمی برای مطالعۀ علل ایجاد مشکلات محیطزیستی و رابطۀ بین سیستمهای محیطز...
In response to the severe situation of water and land resources in China, this paper uses DPSIR (driving force–pressure–state–impact–response) model two-stage network DEA (data envelopment analysis) evaluate carrying capacity utilization efficiency 31 provinces China from 2009 2017. The empirical results show that values most areas do not perform well a downward trend during sample period. Spec...
Abstract Drivers of land use change were captured by the DPSIR model where (D) represented human needs, Pressures (P), activities, State (S), ecosystem, Impact (I) services from ecosystem and Response (R), decisions taken users. Land sat MSS ETM+ (path 185, row 31) used in this study. The image (June 1987, May, 2000 July, 2014) was downloaded USGS Earth Resources Observation Systems data websit...
The Ria Formosa is a shallow mesotidal lagoon on the south coast of Portugal, with natural biogeochemical cycles essentially regulated by tidal exchanges at the seawater boundaries and at the sediment interface. Existing data on nutrients in the water column and the sediment, together with chlorophyll a and oxygen saturation in the water column, are compared using different models for assessing...
