Exploring the Forest Cover Changes and Influential Factors of Dongsithouane National Production Forest Area, Savannakhet Province, Lao PDR

The Dongsithouane National Production Forest (DNPF) is one of the largest natural forest areas in Savannakhet, Lao PDR, which has been a vital support for the local community’s livelihood, Recently, significant changes in land use and land cover (LULC) have been observed in this area, leading to a reduction of natural forests. There were two separate methods of this study: firstly, to identify LULC changes across three different periods, spectral imagery from the Landsat 5 Thematic Mapper (TM) for the years 2001 and 2011, and the Landsat 8 Operational Land Imager (OLI) for 2021 were used as the primary data sources. The satellite images were preprocessed for various forest classes, including pretreatment of the top of atmosphere reflectance by using QGIS software’s semi-automatic classification plug-in (SCP), and ArcGIS was used for post-classification. A supervised classification approach was applied to the satellite images from 2001, 2011, and 2021 to generate diverse maps of LULC. Secondly, a household survey dataset was used to investigate influential factors. Approximately 220 households were interviewed in order to collect socio-economic information (including data on population growth, increased business activities, location of the area, agriculture land expansion, and need for settlement land). Household survey data was analyzed by using SPSS. Descriptive statistics, including frequency distributions and percentages, were applied to observe characteristics. Additionally, a binary logistic regression model was used to analyze the socioeconomic factors related to LULC change in DNPF. Key findings indicated a decline in natural forest areas within the study site. Specifically, both dry dipterocarp forest (−11.35%) and mixed deciduous forest (−0.18%) decreased from 2001 to 2021. The overall accuracy of the LULC maps was 94%, 86%, and 89% for the years 2001, 2011, and 2021 respectively. In contrast, agricultural land increased significantly by 155.70%, while built-up land, and water bodies increased by 65.54% and 35.33%, respectively. The results also highlighted a significant increase in construction land, up to 65.54%. Furthermore, the study found a correlation between agricultural expansion and a reduction of forest areas, along with an increase in built-up land along the forest areas’ boundaries. Timber exploitation and charcoal production also contributed to the decline in forest cover. The logistic regression model identified significant determinants of LULC change, including the area’s location, agricultural land expansion, increased business activity, and the need for settlement land. These factors have influenced the management of DNPF. Urgent sustainable management practices and actions, including forest ecosystem protection, village agricultural zoning, water source and watershed protection and public awareness, are required to preserve the forest areas of DNPF.

A scenario-based clean diesel production strategy for China National Petroleum Corporation

Facing increasingly strict environmental regulations on transportation fuels, China National Petroleum Corporation （CNPC）, the second largest supplier of petroleum products in China, needs to upgrade its transportation fuels. Using the scenario-based analysis method, this paper analyzes how the output and emission related properties, including cetane number, and sulfur and aromatics contents of diesel produced by CNPC, will vary with changes in the configuration of diesel production units in the next 5-10 years. The results showed that, to upgrade its diesel, CNPC needs to adjust its diesel pool by decreasing the share of fluid catalytic cracking （FCC） diesel and increasing the shares of hydrocracking （HDC） and hydrotreating （HDT） diesel. Furthermore, to produce ultra-low-sulfur diesel, straight-run diesel as well as poor diesel blendstocks such as FCC diesel and coker diesel should be hydrotreated before being blended into finished diesel. Developing highly efficient HDC and HDT catalysts and corresponding processes is the key to CNPC economically producing more and cleaner diesel.

A scenario-based clean gasoline production strategy for China National Petroleum Corporation

Facing increasingly strict environmental regulations on transportation fuels, China National Petroleum Corp. （CNPC）, the second largest supplier of petroleum products in China, needs to upgrade its transportation fuels. Using the scenario-based analysis method, this paper analyzes how the emission related properties, including antiknock index, and sulfur, olefin, benzene and aromatics contents of gasoline produced by CNPC, vary with the change in the configuration of gasoline production units in the future 5-15 years. The results showed that for CNPC to upgrade its gasoline, the share of fluid catalytic cracking （FCC） naphtha must be reduced, but just increasing reformate or alkylate and isomerate will result in excessive increase in benzene and aromatics contents or a great loss of gasoline octane number. Therefore, CNPC should suitably control the capacity of its FCC units and increase the capacity of reformer, alkylation and isomerization units. Most importantly, CNPC should dramatically expand the capacity of its hydrotreating or non-hydrotreating gasoline upgrading units to decrease the olefin and sulfur contents in FCC gasoline that takes a dominant share of about 80% in the gasoline pool of China.

Effect of Farming Practices on Honey Production in Boundary of Gishwati Forest National Park

Pesticides and inorganic fertilizers applied in agriculture are key factors which affect biodiversity, especially bees, butterfly and other pollinators. Therefore, this study assessed the effects of farming practices on honey production in boundary of Gishwati Forest National Park in Rwanda. Survey was conducted to collect data from 2000 year to 2018 year from 51 members grouped in UNICOAPIGI beekeeping and 73 members of JYAMBERE agricultural cooperatives to establish the impact of agriculture practice on honey production. The results showed that the change in agricultural inputs from 2000 to 2018 (R2 = 0.901) resulted in high corn yield and consequently induced honey reduction (R2 = 0.75). The correlation coefficients for pesticides and inorganic fertilizers used in corn production had strong negative effects on honey production {γ3 = -0.06 for chemical fertilizers (X3) and γ4 = -0.42 for pesticides (X4)}. JYAMBERE Agricultural cooperative with 75.78% of farmers reported that they used pesticides and inorganic fertilizers in corn production. However, 51 beekeepers grouped in UNICOAPIGI cooperative reported a serious decline of honey production from 27 Kg to 6 Kg of honey per hive after the 2008 year, which is suspected to be mainly the effect from applications of pesticides and fertilizers in corn production. The findings illustrated that the roles of honeybees as pollinator exposed them to toxic, especially pesticides applied in agriculture in boundary of Gishwati national forest reserve, therefore, beekeepers proposed that protection of forests and park is not only sufficient to reach sustainable conservation of bee biodiversity but also requires determining the land use pattern and socio-political factors around the Gishwati forest reserve.

国家战略腹地建设的内涵特征、重大意义和推进策略

面对复杂的国际政治环境和全球产业竞争,立足我国新发展阶段的新特征,我国亟需尽快优化调整重大生产力布局,在广大中西部内陆腹地拓展战略纵深,夯实国家安全基石。2023年12月中央经济工作会议首次提出“建设国家战略腹地”的战略构想,为优化重大生产力布局,保障我国国家安全创造了条件。“国家战略腹地”是相对于前沿地区而言,能为前沿地区提供强大支撑的战略后方,主要是指围绕我国东部沿海起着稳定后方并服务国家战略安全的中西部内陆城市群或相应地区。“国家战略腹地”概念首次在国家层面提出,是党中央从国家发展大局去考量和谋划的,相比其他重大区域战略,国家战略腹地具备地理区位的枢纽性、经济发展的强大韧性、创新发展的引擎性、城市文化的凝聚性等基本特征。从我国区域经济发展史看,“三线建设”“区域协调发展战略”在不同历史时期承担了优化重大生产力布局、维护“大后方”的使命任务,国家战略后方作为新时代“大后方”概念,在新时代语境下自然也被寄予历史重任。进言之,加快推进国家战略腹地建设是当前应对百年大变局的应有之义、构建新发展格局的乘势之举和优化重大生产力布局的破题之策,唯有以自身的确定性应对外部的不确定性,才能把握战略主动。为把战略决策和预期目标变为现实结果,国家战略腹地建设必须系统推进。通过完善战略规划顶层设计、统筹战略物资储备建设、强化战略科技力量支撑、打造战略产业备份基地和建设战略运力空间网络,使之成为我国经济发展的新的增长极和动力源,不断推进新时代大后方高质量发展和高水平安全建设。
