“…Interestingly, the difference in resilience or its components (resistance and recovery) due to a 30-m elevation difference in this paper was similar to that due to a 120–800-m elevation difference in other studies ( Wang et al., 2019 ; Bosela et al., 2020 ; Dell’Oro et al., 2020 ; Du et al., 2022 ). This means that there may be significant drought response differences even in the small-scale terrain, and the amount of difference in resilience-related indicators (recovery, resistance, or resilience) cannot be estimated only by the elevation difference.…”

“…This means that there may be significant drought response differences even in the small-scale terrain, and the amount of difference in resilience-related indicators (recovery, resistance, or resilience) cannot be estimated only by the elevation difference. Other factors may also affect the response of tree growth to drought, thereby causing differences in resilience-related indicators of forests, such as the severity of drought in drought events ( Wang et al., 2019 ; Du et al., 2022 ), altitude range of forests ( Bose et al., 2020 ; Bosela et al., 2020 ), tree species ( Li et al., 2020 ), and tree age ( Wang et al., 2019 ).…”

Understanding the factors affecting the growth of plantation forests can reduce the loss of economic and ecological values caused by plantation forest subhealth. Plantation forests are widely distributed in hilly areas with microtopographic features. Microtopography influences climatic factors associated with plant growth, during not only general time but also extreme events like droughts. However, little research has been conducted on the effects of microtopography on the plantation forest growth. In this paper, we selected Pinus tabulaeformis planted in a hilly site, and studied the effect of microtopography on the climate–growth relationship and drought response of a typical plantation in Northeast China using dendroecological methods. We found: 1) Between hill positions, temperature caused a climatic growth difference. Compared to the hilltop, the correlation of annual growth on the hillside with monthly temperature was more negative in July–August and less positive in January–April. 2) Between aspects, precipitation intensities caused a climatic growth difference. Compared to the sunny slope, the correlation of annual growth on the shady slope with monthly total precipitation below 10 mm/day was less positive (May–June) or more negative (March–April and July), while that with monthly total precipitation above 10 mm/day was more positive in most months.3) Drought response varied significantly based on hill position and aspect. There was no significant difference in resistance between hill positions, while recovery and resilience on the hilltop were greater than those on the hillside.Resistance, recovery, and resilience were all lower on the sunny slope than those on the shady slope. Overall, microtopography exists the effects on the growth of plantation forests, both in terms of climate-growth relationships in general climate and in response to drought when extreme events. Meanwhile, the climatic factors that caused the difference in growth of plantation forests between hill positions and aspects differed. The difference in growth between hill positions was caused by temperature, while that between aspects was caused by precipitation intensity. Drought response difference reflected the legacy effect of drought on plantation growth, which could lead to subsequent changes in climate-growth relationships. These findings demonstrate that strengthening the research of forest trees on microtopography is necessary for accurate carbon sink assessment and precise forest management.

“…The areas with a higher SI were mainly concentrated in the Bashang and high-altitude mountain areas, whereas the SI was low in low-altitude areas, for example, North China Plain. Temperature is the main climatic factor limiting the growth of trees at high altitudes, and the growth of low-altitude trees is mainly affected by precipitation ( Du et al., 2022 ). As future temperature increases, the limiting effect of low temperature on tree growth is augmented at high altitude ( Bai et al., 2019 ).…”

“…The specific objectives of this study were to (1) explore the main environmental factors affecting the larch SI; (2) simulate the larch SI under current and future climate scenarios in the study area; and (3) analyze the suitable growth areas of larch and the future change trend. Generally, temperature limits tree growth at high altitudes, whereas precipitation influences tree growth at low altitudes ( Du et al., 2022 ). Currently, larch is mainly distributed in Bashang Plateau and mountains, and with future climate change, larch tree species would migrate to higher latitudes ( Cheng et al., 2022 ).…”

Larix principis-rupprechtii Mayr (larch) is one of the main afforestation and timber production species used in North China. Climate change has led to a change in its suitable distribution and growth. However, the impact of climate change on its growth suitability is not clear. In this study, using forest resource inventory data and spatially continuous environmental factor data (temperature, precipitation, topography, and soil) in Hebei and Shanxi Provinces, China, the random forest model (RF) was used to simulate the larch site index (SI) and growth suitability under three shared socioeconomic pathways (SSPs: SSP1-2.6, SSP2-4.5, and SSP5-8.5) for the current and future (2021–2040, 2041–2060 and 2080–2100). The results revealed that (1) RF had excellent performance in predicting the regional SI (R2 = 0.73, MAE = 0.93 m, RMSE = 1.35 m); (2) the main factors affecting the productivity of larch were the mean temperature of the warmest quarter (BIO10), elevation (ELEV), mean diurnal range (BIO2), and annual precipitation (BIO12); and (3) larch currently had a higher SI in the Bashang areas and in the high-altitude mountains. The areas characterized as unsuitable, poorly suitable, moderately suitable, and highly suitable accounted for 15.45%, 42.12%, 31.94%, and 10.49% of the total area, respectively. (4) Future climate warming had an obvious inhibitory effect on the SI, and the effect strengthened with increasing radiation intensity and year. (5) The moderately suitable and highly suitable areas of larch growth showed a downward trend under future climate scenarios. By the end of this century, the suitable growth areas would decrease by 14.14% under SSP1-2.6, 15.17% under SSP2-4.5, and 19.35% under SSP5-8.5. The results revealed the impact of climate change on larch growth suitability, which can provide a scientific basis for larch forest management.
