    摘要:

    為緩解人地關(guān)系,以對(duì)黑龍江省威脅最大的土壤侵蝕為切入點(diǎn),,從“三生”視角分析區(qū)域人地系統(tǒng)適應(yīng)性,,并提出基于不同修復(fù)優(yōu)先級(jí)的人地系統(tǒng)修復(fù)方案。首先,,在總結(jié),、梳理適應(yīng)性內(nèi)涵,,整合適應(yīng)性理論與方法基礎(chǔ)上,從“三生”視角提出了基于風(fēng)險(xiǎn)擾動(dòng)的適應(yīng)性分析框架,,將系統(tǒng)適應(yīng)性分解為擾動(dòng),、影響、響應(yīng),、能力4方面,,并從土壤侵蝕風(fēng)險(xiǎn)擾動(dòng)出發(fā),構(gòu)建了系統(tǒng)適應(yīng)性評(píng)價(jià)指標(biāo)體系與評(píng)價(jià)模型,;其次,,采用極差標(biāo)準(zhǔn)化法、克里格插值法,、蔡崇法法和DEA-CCR模型處理數(shù)據(jù),,利用土壤侵蝕方程測(cè)算土壤侵蝕風(fēng)險(xiǎn),利用適應(yīng)性評(píng)價(jià)模型測(cè)算適應(yīng)性指數(shù),,分析土壤侵蝕風(fēng)險(xiǎn)和人地系統(tǒng)適應(yīng)性分布情況,;最后,提出基于不同修復(fù)優(yōu)先級(jí)組合模式的人地系統(tǒng)修復(fù)方案,。結(jié)果表明:黑龍江省土壤侵蝕風(fēng)險(xiǎn)區(qū)面積為1366.61萬(wàn)hm2,,占區(qū)域耕地面積的85.74%,高,、中,、低級(jí)別風(fēng)險(xiǎn)規(guī)模分別為324.02、596.33,、446.26萬(wàn)hm2,。高,、較高級(jí)別人地系統(tǒng)適宜程度區(qū)分布在三江平原東北部和松嫩平原東南部地區(qū),,中級(jí)別分布在大興安嶺和松嫩平原南部地區(qū),低,、較低級(jí)別分布在東南部山地和松嫩平原北部地區(qū),。形成了基于不同修復(fù)優(yōu)先級(jí)組合模式的人地系統(tǒng)修復(fù)方案,其中53個(gè)地區(qū)僅存在1種人地系統(tǒng)修復(fù)方案,,其余27個(gè)地區(qū)在不同優(yōu)先級(jí)組合模式下形成了不同的人地系統(tǒng)修復(fù)方案,,為區(qū)域人地系統(tǒng)修復(fù)提供了多種選擇方案。

    Abstract:

    Heilongjiang Province as the starting point, the adaptability of the regional human-〖JP〗land system was analyzed from the perspective of production-living-ecological, and human-land system restoration schemes were proposed based on different restoration priorities. Firstly, on the basis of summing up and sorting out the connotation of adaptability and integrating the theory and methods of adaptation, a framework for adaptive analysis based on risk disturbance was proposed, which decomposed system adaptability into four aspects: disturbance, impact, response, and capability. Starting from the disturbance of soil erosion risk, a systematic adaptability evaluation index system and evaluation model were constructed. Secondly, the range standardization method, Kriging interpolation method, CAI Chongfa method, and DEA-CCR model were used to process the data, and the soil erosion equation was used to measure the soil erosion risk. The adaptation evaluation model was used to calculate the adaptation index, analyze the soil erosion risk and the adaptive distribution of the human-land system. Finally, a human-land system restoration scheme based on the combination of different restoration priority modes was proposed. The results showed the area of soil erosion risk area in Heilongjiang Province was 13.6661 million hm2, accounting for 85.74% of the area of cultivated land in the region, and the scales of the high, middle and low-level risk scale were 3.2402 million hm2, 5.9633 million hm2 and 4.4626 million hm2. Adaptation areas for high-level and high-level human-land systems suitability areas were distributed in the northeast of the Sanjiang Plain and the southeast of the Songnen Plain, middle levels were distributed in the Daxing’an Mountains and the southern area of the Songnen Plain, and low and lower levels were distributed in the southeast mountains and Northern Songnen Plain. The research formed a human-land system restoration scheme based on different restoration priority combination modes, of which only one kind of human-land system restoration scheme existed in 53 regions, and the remaining 27 areas formed different human-land system restoration schemes under different priority combination modes. The research result provided a variety of options for the repair of regional human-land systems.
