1、XX县城市绿化苗木繁育基地建设可行性研究报告一、项目提要1、项目名称：江西省XX县城市绿化苗木繁育基地2、项目单位：江西省XX县林业局3、项目联系人：王玮4、建设地点：中云镇至XX县城(紫阳镇)公路干线两旁5、建设规模：1000亩风景园林绿化苗木基地，200亩花卉及草坪圃地，总规模1200亩。6、建设期限：建设期2年，第一年完成基础设施建设、整地、播种、育苗和部分苗木栽植工作，第二年完成苗木移栽、嫁接、培育等工作。7、合作方式：独资、合资、合作二、建设条件1、自然条件：XX县位于江西省东北边隅，地处赣、皖、浙三省交界处。全县土地总面积450万亩，其中：林业用地面积376万亩，耕地面积33.7万
2、亩。境内山峦起伏，群山纵横，以山地、丘陵为主，是一个典型的江南山区县。XX县属东南季风温暖湿润气候，年平均气温16.7，极端最高气温41，极端最低气温11，年平均降水量1821毫米，年平均无霜期252天，年平均日照1868小时。境内水网纵横，分布稠密，水资源极为丰富。地表水量丰盈，平均径流量32.01亿立方米。土壤主要有红壤、黄壤、水稻土、冲积土和草甸土等五种类型，山地土壤种类以红壤和黄壤为主，成土母岩多为板岩、页岩和花岗岩等。XX县植被类型主要有常绿阔叶林、针叶林、针阔混交林、灌木林等。主要乔木树种有：杉木、马尾松、苦槠、栲树、枫香、木荷、栎类、拟赤杨、南酸枣、毛竹、油茶等。灌木树种主要有：
3、白栎、杜鹃、黄端木、乌饭、山苍子、赤楠、紫穗槐、乌药等。草木植物主要有铁芒箕、蕨类以及禾本科草本等。据1999年分类区划调查，全县活立木蓄积860万立方米，毛竹1957万根，森林覆盖率81.5%。2、交通条件XX县境内公路纵横交错，全县共有公路140多条，通车里程1500多公里，公路主干线有三条：婺景线、婺溪线、王赋线。基本上村村通公路，大部分公路实现了路面硬化、路旁绿化。东、北可达安徽黄山和浙江等地，南到上饶，西通景德镇、九江，交通十分便捷。随着两条高速公路在我县的开工，未来其交通状况将日趋发达。3、社会经济条件XX县总人口32.31万人，其中农业人口27.14万人，非农业人口5.17万人，
4、农村劳动力12.76万人。2001年全县工农业总产值11.77亿元，其中林业产值1.59亿元，上缴财政0.76亿元，人均年收入2600元。XX县林业局主管全县林业工作，下设营林股、林政股、计财股、防火办、绿化办等职能股(室)，另有林业调查设计队、森防站、种苗站、技术推广站、林业工作站、森林公安分局等行政事业机构，林业管理机构比较齐全。全县有国有林场6个，乡村林场119个，林业系统职工3000余人。林业系统技术力量雄厚，有工程师28人，助理工程师62人。三、基地建设的可行性与必要性XX县有着优越的自然环境条件和丰富的物种资源，交通四通八达，区位优势明显，林业技术力量和林业科技支撑有一定的基础。近
5、几年来，我县先后实施了国家重点森林生态效益补助资金试点项目、长江防护林工程、退耕还林工程，每年工程造林在3万亩以上，培育和造就了一大批林业科技队伍。国土绿化，苗木是基础，目前我国城市建设发展迅速，城市化和城镇建设步伐加快，人们愈来愈追求人与自然的和谐，需要良好的自然生态环境，而城市绿化美化是国土绿化的重要组成部分，为此，城市绿化美化需苗量将剧增，绿化苗木市场潜力大，这正是建国以来，绿化苗行业面临的最好机遇。XX县有很多优良、珍贵、速生的阔叶树种，种质资源十分丰富，建设大、中型绿化苗木繁育基地有着得天独厚的条件。同时，该项目的实施，对调整我县林业产业结构，加快林业建设步伐，增加就业机会，带动农民
6、脱贫致富奔小康，提供了有效的途径。四、建设内容与规模(一)建设内容1、苗圃地选择：苗圃地选在公路干线旁边，靠近居民点，交通方便的地方，要求地势平坦，排灌水良好，土壤以结构疏松、透水透气性良好的砂壤土为好，土层厚度要在50厘米以上。2、树种选择：绿化树种以阔叶树种为主，如香樟、桂花、红豆杉、杜英、红楠、淅江楠、广玉兰、合欢、无患子、元宝枫、马褂木、七叶树、圆柏、桧柏等。木本花卉品种可选择：杜鹃、茶花、紫微、红花木继木、蜡梅、紫藤、小檗、黄杨、女贞、海桐等。草木花卉品种可选择花色多样、丰富多彩的品种，用来制作插花和切花之用。草坪草品种如马尼拉、马蹄金、高羊毛等。3、苗期田间管理：主要是做好播种、栽
7、苗、移植、除草、间苗、开沟、排水、灌溉、施肥、修剪、定形、嫁接等工作，冬季做好防冻工作，夏季做好遮荫防晒工作，积极搞好病虫害防治工作。(二)建设规模与地点：建设1000亩的风景绿化苗木基地、150亩的花卉苗木繁育基地、50亩的草坪繁育基地，总规模1200亩。基地分布中云镇至XX县城公路干线两旁。(三)管理服务机构为加强本项目的管理，确保项目顺利实施，XX县成立项目领导小组，由县领导、县直有关单位负责人、项目建设单位主要负责人组成，主要是做好项目的跟踪服务，部门间的协调等工作，创造一个良好的投资环境。五、投资估算依据当地社会经济条件技术指标综合确定。项目总投资需4000万元，包括前三年的整地、苗
8、木、栽植、施肥、管理、科技支撑等费用。具体投资如下：1、土地承包费：按每年每亩350元计算，承包期30年，1200亩的投资额为1260万元；2、土地平整、道路拓宽等前期工作费300万元；3、办公用房、办公设备、水电排灌设施、工程车辆大概需要700万元；4、管理技术人员和民工工资以及培训考察费用大概需要300万元；5、建造一座大型玻璃温室约需300万元；6、塑料大棚成本费约需240万元；7、种苗费(包括种子、苗木)约需530万元；8、肥料、农药、生产工具等生产资料费约需300万元；9、不可预见费70万元；六、效益分析1、经济效益分析项目实施后，花卉和草坪，当年投资，当年就可盈利，200亩的花卉和
9、草坪当年产值就可达100万元以上。绿化苗木生产周期较长，一般需2至3年或更长时间，也就是说要到第三年才可出圃盈利，第三年按每亩产值1万元，当年总产值就可达1000万元以上，而且随着培育年限的增加，其产值将逐年增加。预计项目实施第六年可以收回全部投资成本，经济效益十分明显。2、生态效益分析因中云镇至XX县城公路沿线两边是我县生态比较脆弱的地区，项目建成后，将有效治理和改善当地生态环境，对调节气候、涵养水源、保持水土、扩大森林植被起到极大促进作用，尤其是对美化绿化公路沿线，实施我县绿色通道工程建设增加一道亮丽的风景线。3、社会效益分析项目实施后，项目区农民可以增加劳务收入，创造就业机会，消化剩余劳
10、动力，从而加快我县农民脱贫致富奔小康的步伐，促进我县农村的繁荣与稳定。项目建设符合当前林业发展方向，对挖掘林业生产潜力，调整林业产业结构，实现林业跨越式发展起到推进作用，是适合我县县域经济发展道路的一项重大举措。七、项目建设保障措施XX县委、县政府对项目实施非常重视，采取了各项优惠政策，在土地征用、土地承包、资金投入、施工组织、劳动力投入，宣传发动，科技和信息管理等方面都将会给予有力的支持。项目建设单位管理机构健全，技术力量雄厚，有丰富的项目管理和项目实施经验，这一切可为项目的实施提供可靠的保障。Editors note: Judson Jones is a meteorologist, jo

13、 I was heartbroken. Yet the privatized space race has renewed my childhood dreams to reach for the stars.As a meteorologist, Ive still seen many important weather and space events, but right now, if you were sitting next to me, youd hear my foot tapping rapidly under my desk. Im anxious for the next

15、ch man jump from 96,000 feet Tuesday, I sat at work glued to the live stream of the Red Bull Stratos Mission. I watched the balloons positioned at different altitudes in the sky to test the winds, knowing that if they would just line up in a vertical straight line we would be go for launch.I feel th
16、is mission was created for me because I am also a journalist and a photographer, but above all I live for taking a leap of faith - the feeling of pushing the envelope into uncharted territory.The guy who is going to do this, Felix Baumgartner, must have that same feeling, at a level I will never rea
17、ch. However, it did not stop me from feeling his pain when a gust of swirling wind kicked up and twisted the partially filled balloon that would take him to the upper end of our atmosphere. As soon as the 40-acre balloon, with skin no thicker than a dry cleaning bag, scraped the ground I knew it was
18、 over.How claustrophobia almost grounded supersonic skydiverWith each twist, you could see the wrinkles of disappointment on the face of the current record holder and capcom (capsule communications), Col. Joe Kittinger. He hung his head low in mission control as he told Baumgartner the disappointing
19、 news: Mission aborted.The supersonic descent could happen as early as Sunday.The weather plays an important role in this mission. Starting at the ground, conditions have to be very calm - winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule att

It will climb higher than the tip of Mount Everest (5.5 miles/8.85 kilometers), drifting even higher than the cruising altitude of commercial airliners (5.6 miles/9.17 kilometers) and int

As he crosses the boundary layer (called the tropopause), he can expect a lot of turbulence.The balloon will slowly drift to the edge of space at 120,000 feet (22.7 miles/36.53 kilometers). Here, Fearless Felix will unclip. He will roll back the door.Then, I would assume, he will

Like hitting the top of the water, he will begin to slow as he approaches the more dense air closer to Earth. But this wil
24、l not be enough to stop him completely.If he goes too fast or spins out of control, he has a stabilization parachute that can be deployed to slow him down. His team hopes its not needed. Instead, he plans to deploy his 270-square-foot (25-square-meter) main chute at an altitude of around 5,000 feet
25、(1,524 meters).In order to deploy this chute successfully, he will have to slow to 172 mph (277 kph). He will have a reserve parachute that will open automatically if he loses consciousness at mach speeds.Even if everything goes as planned, it wont. Baumgartner still will free fall at a speed that w
26、ould cause you and me to pass out, and no parachute is guaranteed to work higher than 25,000 feet (7,620 meters).It might not be the moon, but Kittinger free fell from 102,800 feet in 1960 - at the dawn of an infamous space race that captured the hearts of many. Baumgartner will attempt to break that record, a feat that boggles the mind. This is one of those monumental moments I will always remember, because there is no way Id miss this.
