秦岭是中国的“中央水塔”,研究秦岭北麓矿山生境质量的时空演变特征对区域生态保护和可持续发展意义重大。为了评估小流域背景下人类活动对矿山生态环境的影响,该研究针对沣河流域内的重点工程祥峪铁矿区,基于遥感影像提取其1985、2002...秦岭是中国的“中央水塔”,研究秦岭北麓矿山生境质量的时空演变特征对区域生态保护和可持续发展意义重大。为了评估小流域背景下人类活动对矿山生态环境的影响,该研究针对沣河流域内的重点工程祥峪铁矿区,基于遥感影像提取其1985、2002、2010年和2022年土地利用变化,结合InVEST(integrated valuation of ecosystem services and tradeoffs)模型和地理探测器定量分析该矿区生境质量变化与驱动因素。结果表明:祥峪铁矿区的土地利用变化主要由旱地逐步转变为林地和工业用地,疏林地转入面积达到18245505.71 m^(2),退耕还林还草工程取得显著成效;祥峪铁矿区生境质量指数由0.50下降为0.49,标准差由0.06增加为0.09,说明生境质量有所下降,空间差异不断扩大,区域整体平均生境退化度降低,但工业用地迅速扩张对周边林地产生持续影响;生境质量变化是自然因素和人文因素共同作用的结果,其中,土地利用变化是造成生态环境脆弱的主要原因,对生境质量变化的解释力达到0.82。该研究可为分析其他类似矿区生态环境演变,推动景观格局的优化和生态文明建设提供科学参考。展开更多

Used Stratified Random Sampling and data was collected from both primary and secondary data (both quantitative and qualitative data. The data analyzed used qualitative and quantitative analysis. The supply chain analysis was carried out to develop a description of the value chain to identify potential high-value market areas and current and potential products in the domestic and export markets. The results of the study revealed that most farmers in the research location grow different types of crops and livestock. In particular for Aileu and Ainaro where most of the areas are up-land, therefore, horticulture crops (mustard, cabbage, carrots, and tomato) and coffee are dominated in these areas. For Manufahi, some parts are lowland areas, where most crops grown are maize, cassava, and paddy rice. The study reveals that local potential agriculture products and livestock in the municipalities of Aileu, Ainaro, and Manufahi are vegetable, coffee, maize, and paddy rice, banana, shallot, tangerine, cabbage, carrot, cattle, mung-bean, and banana. To accelerate economic growth, in these municipalities, there is a need to modernize agricultural production, requiring markets for both inputs supply and for the sale of output products. Opportunities to increase the productivity of these products are feasible and this can be done through the use of high-variety seeds and better farm management, and the government and private sector can play an important role in improving productivity as this will have a further implication in improving food security.展开更多
高潜水位矿区采矿活动及城镇化发展会导致土地利用类型明显变化,进而影响矿区的固碳能力。采用潘谢矿区2002-2021年5期土地利用数据,利用FLUS(Future Land Use Simulation)模型,选取了采矿、社会经济和气候环境等方面数据作为驱动因子,...高潜水位矿区采矿活动及城镇化发展会导致土地利用类型明显变化,进而影响矿区的固碳能力。采用潘谢矿区2002-2021年5期土地利用数据,利用FLUS(Future Land Use Simulation)模型,选取了采矿、社会经济和气候环境等方面数据作为驱动因子,分别预测了自然发展和生态保护两种情景下2028年土地利用变化,再结合InVEST(Integrated Valuation of Ecosystem Services and Tradeoffs)模型,计算了潘谢矿区2002-2021年的历史碳储量以及2028年不同情景下的未来碳储量,并对潘谢矿区碳储量的时空变化特征进行了分析。结果表明:(1)2002-2021年潘谢矿区土地利用变化表现为耕地不断减少,湿地和建筑用地持续增加,其中耕地减少了147.93 km^(2),湿地和建筑用地分别增加了71.01 km^(2)和75.76 km^(2)。在此期间,潘谢矿区碳储量减少了1.62×10^(5)t,减少幅度为3.83%,其中在2018-2021年碳储量下降最快。(2)预测结果显示,2028年2种情景下研究区内土地利用变化均为湿地和建筑用地持续增加,耕地不断减少。但相较于自然发展情景,生态保护情景下矿区内耕地受到保护,面积有所增加,湿地和建筑用地的增长减缓。与2021年相比,自然发展情景下的碳储量减少了0.74×10^(5)t,生态保护情景下的碳储量减少了0.53×10^(5)t。研究结果表明,受采煤沉陷和城镇发展影响,沉陷湿地和建筑用地扩张导致耕地减少是碳储量下降的主要原因,采取生态保护措施能够在一定程度上减缓碳储量的下降。展开更多
