Abstract

Abstract This study aims to evaluate land use and land cover (LULC) changes and associated impacts in the landscape structure and ecosystem services (ES) value in Lousã municipality, in Central Portugal. The results show that significant changes in LULC were recorded over the study period (1974–2018). Agricultural abandonment, expansion of woodland due to the promotion of the eucalyptus (EU) monoculture (chiefly Eucalyptus globulus), the invasion of exotic species (mainly Acacia dealbata) and the increase of built-up areas are the most significant changes that have shaped the landscapes of the study area. The analysis also revealed that the mean patch size has decreased whereas the number of patches increased. The results showed that although the EU and deciduous forest (DF) increased the ES value, the overall total ES value fell around 10% between 1974 and 2018, mainly due to the decrease in the supply of agricultural goods. Studies of this kind on local rural landscapes are vital when it comes to devising appropriate land management policies for the landscape level by considering the interaction between each element for sustainable development.

土地利用变化对当地景观结构和生态系统服务的影响——以葡萄牙中部为例

摘要本研究旨在评估葡萄牙中部卢昂市的土地利用和土地覆盖（LULC）变化及其对景观结构和生态系统服务（ES）价值的相关影响。结果显示，在研究期间（1974年至2018年），LULC发生了显著变化。农业废弃、桉树（欧盟）单一栽培（主要是蓝桉）的推广导致的林地扩张、外来物种（主要是金合欢）的入侵以及建成区的增加是塑造研究区景观的最显著变化。分析还显示，平均补丁大小有所减少，而补丁数量有所增加。结果显示，尽管欧盟和落叶林（DF）增加了ES值，但1974年至2018年间，总ES值下降了约10%，主要是由于农产品供应减少。当考虑到可持续发展的每个要素之间的相互作用，为景观层面制定适当的土地管理政策时，对当地农村景观的此类研究至关重要。

期刊介绍： Quaestiones Geographicae was established in 1974 as an annual journal of the Institute of Geography, Adam Mickiewicz University, Poznań, Poland. Its founder and first editor was Professor Stefan Kozarski. Initially the scope of the journal covered issues in both physical and socio-economic geography; since 1982, exclusively physical geography. In 2006 there appeared the idea of a return to the original conception of the journal, although in a somewhat modified organisational form. Quaestiones Geographicae publishes research results of wide interest in the following fields: •physical geography, •economic and human geography, •spatial management and planning,
