越南Ha Nam省近十年来土地利用变化研究

作者：陈锋武（Tr(?)n Phong v(u|~)）重庆交通大学

学位级别：硕士

HaNam省地处越南北部，位于红河平原，介于20020’-20045’N和105045’-106010’E之间。HaNam省下辖Phu ly、Duy Tien、Binh Luc、Kim Bang、Thanh Liem、ly Nhan，共5县1市。HaNam省的总面积为86018.33ha占全国土地面积的0.25%及红河平原土地面积的6.6%。根据，越南资源与环境部的土地分类标准，越南HaNam省土地利用类型多样，共包括3个一级地类，13个二级地类。一级用地类型分为农业用地、非农业用地、未利用地，二级分类包括农业产出用地、林地、水产养殖用地、其他农业用地、居住用地、专用设施用地、信仰用地、坟地、水系及专用水面、其他非农业用地、平地未利用地、山丘未利用地、石山未树林。虽然，HaNam省面积较小，但2000年以来的工业化、现代化等政策已影响到HaNam省的土地利用迅速变化。因此，本文的研究目的是在研究越南HaNam省的土地利用变化趋势的基础上提出土地利用优化对策与建议。本文以越南HaNam省为研究区，根据遥感影像、数字高程模型和县域政区图件等数据，采用单一土地利用态度、Gibbs-Martin多样化指数、城市扩展程度、人口-城市扩展指数等定量指标和土地利用转移矩阵对越南HaNam省近10年来的土地利用进行了分析，并应用马尔科夫预测模型来预测HaNam省的2020年土地利用变化，所得的主要结论如下： (1)从2000-2010年，农业用地面积从61325.21ha减少到56104.28ha，面积减少了5220.93ha，年变化面积为522.09ha。农业用地减少的原因是经济的快速发展和城市化进程的不断加快，大量的农业用地变为城镇用地。在农业用地面积大量持续减少的同时，农业用地面积在整个省面积的比重也不断下降，从2000年的72.37%下降到2010年的65.2%。随着HaNam省社会经济的快速发展，HaNam省的非农业用地面积显著增加，其中面积增加最大的用地类型是居住用地和专用设施用地。从2000-2010年，居住用地面积从4281.39ha增加到5378.6ha，10年变化面积为1097.21ha，年变化面积为109.72ha，专用设施用地面积从10368.54ha增加到14890.4，变化面积达4521.86ha，年变化面积为452.19ha。这两种土地类型面积迅速增加的原因是为满足经济快速发展的需要，HaNam省加大了基础设施建设，从而使得道路、交通、机关等用地面积增加趋势显著;经济发展促进了人民物质和文化生活水平的不断提高，城镇住宅建设得到发展和改善。未利用地包括三种土地类型平地未利用地、山丘未利用地、石山无树木覆盖。从2000-2010年，未利用地面积从2308.73ha增加到3806.5ha，变化面积为1497.77ha，占全省面积的比重从2000年2.72%到2010年的4.42%。虽总面积增加但二级土地利用类型平地利用地和山丘未利用地面积是减少的，10年内面积分别减少为19.2ha和635.69ha。只有石山无树木覆盖面积是增加的，从2000年的302.81ha到2010年的2455.47ha，年变化面积为215.27ha。 (2) HaNam省在2000年的土地利用程度指数总体上不高，2000-2005年间的土地利用程度变化比较小， I为2.62，2005-2010年间的土地利用程度变化比较明显， I为6.12，说明这时间段该地区加强了土地资源开发利用度，土地利用类型变化较快。 (3)土地利用转移矩阵的分析结果表明HaNam省城市化过程不仅是大量农业用地转变为非农业用地的过程，同时也包含非农业用地之间的调整和转化，主要是转化为居住用地和专用设施用地。从2000到2010年，农业产出用地面积的流出量为4349.69ha，其中转变为居住用地和专用设施用地的面积共有3402.01ha，占农业产出用地面积总流出量的78.21%;转变为未利用地的面积为7259.23ha。在非农业用地之内有水系及专用水面转化为居住用地及专用设施用地的面积分别为25.13ha和45.13ha，居住用地和专用设施用地相互转化面积为85.37ha和22.73ha。 (4)应用马尔科夫(Markov)预测模型预测2010至2020年间HaNam省土地利用类型变化情况。预测结果表明，HaNam省土地利用格局的未来发展趋势为:居住用地、专用设施用地、石山未树林将继续保持增加的趋势;水产养殖用地、其他农业用地、信仰用地、坟地、其他非农业用地在波动变化中有所增加;农业产出用地、林地继续保持减少的趋势;平地未利用地、山丘未利用地面积逐步减少。 (5)提出了越南HaNam省土地利用存在的三个大问题：①农业用地面积大量转化为城镇用地②林地用地面积减少大部分面

Diversity in the biophysical and socio-economic attributes of agricultural systems makes them uniquely niche based. Farmers are expert in local biophysical and socio-economic situations and can contribute in developing pragmatic indicators of agro-environmental development. During evaluation of an agricultural research project in Yunnan, China, local farmers were capable of evaluating the effects of modified technologies on existing cropping systems and discussed their attitudes to the interventions using their own indicators. Farmers＇ response can be grouped into seven major aspects： i） effects on income, ii） effects on production resources, iii） effects on crop management, iv） existing local knowledge about the technology, v） availability of inputs, vi） access to information, and vii） socio-economic conditions of farming households. Farmers concluded that environmental conditions in the experimental catchment in comparison to an adjacent untreated catchment were better in terms of soil and water losses, vegetation cover and natural resources, infrastructures and catchment management, use of environmentally-friendly technologies, and crop productivity. Success in soil and water conservation programmes depends on the efforts of the farmers and other local users and their greater involvement helps to identify more pragmatic indicators. Furthermore, it increases ownership of the programme, enhances interactions with the project scientists, increases farmers＇ awareness of ago-environmental problems and their possible consequences. These development will enable scientists to develop better targeted interventions and increase the likelihood of adoption of tested technologies by local communities. The use of paired adjacent catchments improved evaluation activities and is proposed as good practice for future catchment improvement programmes.

Purpose: Selective laser sintering (SLS) is a rapid pro- totyping technique applied to produce tissue-engineer- ing scaffolds from powder materials. The standard scanning technique, however, often produces struts of extensive thickness, which means fabrication of high- ly porous scaffolds with small overall dimensions is quite difficult. Nevertheless, this study aims to overcome this shortfall. Design/methodology/approach: To this end, three scanning methods were evaluated in terms of minimum feature size and freedom of design, using a test polyamide (PA) material. Polycaprolactone (PCL) was then employed to create highly porous 3D scaffolds using the preferred scanning me- thod to produce thin struts. Findings: While in normal scanning mode some features were well above the laser spot diameter, strut thicknesses below the laser spot diameter were achieved when using the “outline scan” function for PA material. Those achieved for PCL were slightly higher and in the 500-800 ?m range, with an average pore size of 400 μm. Investigations on the properties of the scaffolds revealed an effective compression modulus of the PCL scaffold of 6.5 MPa. Furthermore, there was no change in physical or che- mical properties when the scaffolds were stored in a physiological environment for 7 weeks. Originality/ value: Though SLS is considered as a fabrication te- chnique for tissue engineering scaffolds, actually pro- duced scaffolds did not comply with porosity requirements and limitations of the SLS process in produ- cing features at the size of the laser beam spot have not been discussed. The present paper shows the capabilities of the SLS process based on two materials and presents a method to minimize feature size in scaffolds.

Objective: The main objective was to study the disturbances of the Blood Count of children hospitalized in the general pediatric of the Gabriel Touré teaching hospital. Methods: This was a prospective and descriptive study conducted from September 1 to November 30, 2018 in the general pediatrics department of the Gabriel Touré teaching hospital in Bamako. Data were collected on patient records using a survey sheet. Results: We collected 512 files of children out of 1030 admissions during the study period;the rate of completion of the blood count is 50%. The male sex was predominant with a sex ratio of 1.3. The majority of patients were under 5 years old (58%). The majority of fathers (56%) and mothers (64%) of children had no education;they are mainly farmers (61%) and housewives (88%). Pallor was the reason for consultation in 29% of patients and present in 60%. On blood count, anemia was present in 92% of patients, half of whom (50%) had severe anemia with a hemoglobin level below 7 g/dL. The anemia was mainly microcytic (72%) and hypochromic (66%). Hyperleukocytosis (62%), eosinophilia (68%) and basophilia (58%) were the abnormalities observed in the white line. Thrombocytopenia accounted for 40%. Severe malaria (53%) was the main discharge diagnosis and almost all patients (99%) were alive at discharge. Conclusion: The characteristics of anemia require a study of the complete blood count in healthy children with dosage of serum iron and ferritin for a better understanding of the phenomenon.
