【摘要】:沙漠化地區(qū)生態(tài)環(huán)境十分脆弱,理解農(nóng)戶對生態(tài)變化的感知與適應策略選擇傾向對于制定科學的生態(tài)環(huán)境治理政策至關重要。采用參與式的農(nóng)村評估法(PRA)對地處庫布其沙漠腹地的杭錦旗不同區(qū)域農(nóng)戶的生態(tài)環(huán)境變化感知與適應進行了調查與對比分析。結果發(fā)現(xiàn):與2000年相比,大部分農(nóng)戶認為當?shù)氐纳鷳B(tài)環(huán)境好轉了。其中,牧區(qū)受訪戶對生態(tài)好轉的認知度低于農(nóng)區(qū);為改善生態(tài)環(huán)境,農(nóng)戶在生態(tài)保護政策的引導下,采取了向二三產(chǎn)業(yè)轉移勞動力、改變養(yǎng)殖模式、減少牲畜數(shù)量、抽取地下水、精耕細作等措施應對生態(tài)環(huán)境變化。除精耕細作外,牧區(qū)農(nóng)戶采用其他適應策略的比例均遠高于農(nóng)區(qū);農(nóng)戶對生態(tài)環(huán)境變化的感知與適應具有區(qū)域差異性和空間層次性,農(nóng)戶對經(jīng)濟機會的響應影響著其對生態(tài)環(huán)境變化的感知與適應策略選擇,并在此基礎上提出了改善當?shù)厣鷳B(tài)環(huán)境的政策建議。
[Abstract]:The ecological environment in desertified areas is very fragile. It is very important to understand the farmers' perception of ecological changes and their tendency to choose adaptive strategies for the formulation of scientific ecological environment management policies. A participatory rural assessment method was used to investigate and analyze the ecological environment change perception and adaptation of farmers in different regions of Hangjin Banner located in the hinterland of Kubuqi desert. The results showed that compared with 2000, most farmers thought the local ecological environment had improved. In order to improve the ecological environment, farmers, under the guidance of the ecological protection policy, adopted the transfer of labor to the secondary and tertiary industries, changed the breeding model, and reduced the number of livestock. Extraction of groundwater, intensive cultivation and other measures to cope with ecological environment changes. With the exception of intensive cultivation, the proportion of farmers adopting other adaptation strategies in pastoral areas is much higher than that in agricultural areas, and farmers' perception and adaptation to ecological changes have regional differences and spatial hierarchies. Farmers' response to economic opportunities affects their perception of ecological environment changes and the choice of adaptation strategies, and on this basis puts forward policy recommendations to improve the local ecological environment.
