【摘要】：草原是一種重要的生態(tài)經(jīng)濟(jì)資源,如果能夠充分合理的利用,人類就會(huì)獲得非常可觀的經(jīng)濟(jì)和生態(tài)效益。關(guān)山草地資源非常豐富,但是長(zhǎng)期以來,由于自然因素和人為因素的綜合作用,草原退化嚴(yán)重,生態(tài)環(huán)境持續(xù)惡化,嚴(yán)重影響了草原畜牧業(yè)的發(fā)展和農(nóng)牧民收入水平的提高。因此,科學(xué)評(píng)價(jià)不同因素對(duì)草原退化的影響,提出合理的遏制草原退化的策略,對(duì)促進(jìn)草地資源的可持續(xù)利用,具有十分重大的意義。本研究通過實(shí)地調(diào)查和資料查找等方式,了解了關(guān)山草原地區(qū)的草地資源基本概括和草地類型、分布等特征;并在此基礎(chǔ)上對(duì)關(guān)山地區(qū)草原形成的機(jī)制、草場(chǎng)退化機(jī)制及影響因素等進(jìn)行分析;根據(jù)草原退化程度,對(duì)草原進(jìn)行分區(qū)(限制性經(jīng)營(yíng)保護(hù)區(qū)、半開放輪牧區(qū)和開放型輪牧區(qū));結(jié)合關(guān)山草原的生態(tài)條件計(jì)算出草原的理論載畜量,并與其現(xiàn)實(shí)載畜量進(jìn)行了比較;提出退化草原生態(tài)修復(fù)工程和草原可持續(xù)發(fā)展措施,為關(guān)山草原退化生態(tài)系統(tǒng)修復(fù)、草原的可持續(xù)利用提供理論依據(jù)。根據(jù)研究結(jié)果和總結(jié)以往草原恢復(fù)措施的經(jīng)驗(yàn)教訓(xùn),提出了關(guān)山草原可持續(xù)利用的政策建議。只有實(shí)現(xiàn)人口增長(zhǎng)、經(jīng)濟(jì)發(fā)展與草原環(huán)境相適應(yīng),合理利用草原,保持關(guān)山草原生態(tài)系統(tǒng)良性健康的發(fā)展,才能保證其作為當(dāng)?shù)刭囈陨娴闹匾男竽翗I(yè)基地,促進(jìn)關(guān)山草原地區(qū)社會(huì)、經(jīng)濟(jì)、環(huán)境的協(xié)調(diào)發(fā)展。
[Abstract]:Grassland is an important ecological and economic resource. If we can make full and reasonable use of it, human beings will get very considerable economic and ecological benefits. The grassland resources in Guanshan are very rich, but for a long time, Due to the combination of natural and human factors, grassland degradation is serious and ecological environment continues to deteriorate, which seriously affects the development of grassland animal husbandry and the income level of farmers and herdsmen. It is of great significance to scientifically evaluate the influence of different factors on grassland degradation and put forward reasonable strategies to curb grassland degradation, which is of great significance to promote the sustainable utilization of grassland resources. The basic summarization of grassland resources, grassland types and distribution characteristics in Guanshan grassland area are understood. Based on this, the mechanism of grassland formation, grassland degradation mechanism and influencing factors in Guanshan grassland area are analyzed. The grassland is divided into three areas (restricted management reserve, semi-open rotational grazing area and open rotational grazing area), and the theoretical stocking capacity of the grassland is calculated according to the ecological conditions of Guanshan grassland, and compared with the actual stock carrying capacity. In order to provide theoretical basis for restoration of degraded grassland ecosystem and sustainable utilization of grassland in Guanshan grassland, ecological restoration engineering and sustainable development measures of degraded grassland are put forward, and the experiences and lessons of previous grassland restoration measures are summarized according to the results of the research. The sustainable utilization of Guanshan grassland is proposed. Only by realizing population growth, adapting economic development to grassland environment, making rational use of grassland, maintaining healthy and healthy development of Guanshan grassland ecosystem, In order to ensure its survival as an important animal husbandry base, promote the coordinated development of society, economy and environment in Guanshan grassland area.
