“…Analisis carrying capacity DAS merupakan faktor utama dalam perencanaan pengelolaan DAS baik dari aspek fisik maupun aspek sosial ekonomi serta tata kelola DAS (Noywuli et al, 2019). Indeks daya dukung DAS menjadi dasar analisis untuk mengetahui kemampuan DAS dalam mendukung pemenuhan kebutuhan manusia serta pada saat yang sama dapat melakukan perlindungan sumberdaya yang ada di DAS.…”

One of the priority watersheds in Southeast Sulawesi is the Poleang watershed. It is necessary to assess management performance to remain sustainable in its implementation. This research aims to determine the performance of poleang watershed management based on indicators of land conditions and determine recommendations for the direction of sustainable land management policies. The survey methods used in the research and analysis include land criticality, land cover and erosion in calculating carrying capacity. This research resulted in the fact that the land support in the Polean g watershed had a high class with a score of 1.25 based on the critical land sub-criteria. Sub-land cover criteria have an excellent category with a score of 0.5, and the erosion index sub-criterion has a very high category with a score of 1.5. Overall, the carrying capacity of the Poleang watershed is in the moderate category, so it is necessary to maintain land or increase the area of vegetation cover of the Poleang watershed through the application of vegetation conservation methods, technical conservation methods and mechanical conservation methods.

“…Methods such as the ETCC model [ 27 ], spatial analysis methods of geographic information systems (GIS) and scoring methods [ 28 ], the descriptive method [ 29 ], and spatial dynamics model [ 30 ] are mainly adopted. The scale mainly involves watershed [ 31 , 32 ], provinces [ 33 ], and counties [ 34 ]. In China, the content primarily aims at the definition of concept connotation [ 35 ], the analysis of regional dynamic evolution [ 36 , 37 , 38 ], and the diagnosis of influencing factors [ 39 , 40 ]; the methods mainly include the evaluation of ecological sensitivity [ 41 ], the projection pursuit model [ 42 , 43 ], the improved ecological footprint model [ 44 , 45 ], the fuzzy comprehensive evaluation method [ 46 ], and the TOPSIS model [ 47 , 48 ]; the scale principally includes large and medium-sized urban agglomeration [ 49 , 50 ], central cities [ 51 ], and typical functional area [ 52 ].…”

With the acceleration of urbanization, the construction land scale of urban and rural areas is constantly expanding, which leads to contradiction and conflict between territorial development and ecological protection becoming more and more serious. Therefore, as an important unit of county (district), and even urban and rural, development, the study on land resource carrying capacity and the rationality of the development can provide some basis for developing the optimal strategies of differential territorial space. Taking Xifeng, Gansu Province, China as the research area, this study constructs the evaluation index system of township construction land carrying capacity from the three dimensions of ecological protection, natural environment, and social economy. It evaluates the suitability of township construction land by the means of a comprehensive scoring method and discusses the carrying capacity and spatial pattern matching of township construction land based on the suitability evaluation results. The results showed that: (1) the spatial difference of suitability of construction land is obvious, which is higher in the city center than in the surrounding areas; (2) the comprehensive carrying capacity of township construction land is 52.62%, and different townships range from 3.78% to 13.15%. It is different between towns; (3) on the whole, the condition of township construction land is well-developed, and the main distribution forms are flaky, banded, and dotted. (4) There is a positive correlation between spatial matching and carrying capacity. The carrying capacity should be considered in regional development to avoid overdevelopment. It can provide a basis for optimizing the territorial spatial layout, strengthening the coordinated development among townships, and improving the comprehensive township carrying capacity in the Loess Plateau hilly and gully region.

“…Forest removal in the seasonal tropical montane forest resulted in typically increasing mean annual water yield and decreasing dry-season flows (Peña-Arancibia et al, 2019). Noywuli et al (2019) reported that the forest-removal upstream watershed in Indonesia had a low carrying capacity condition indicated prominently by drought.…”

The research assessed water storage in a dry dipterocarp forest (DDF) with enriched 34-year-old pine planting and the role of pine. Plant surveys were carried out using 10, 40×40 m2 plots, and data were obtained by measuring tree stem girths and heights. Plant features, biomass, and stored water amounts were measured. Fresh plant samples of abundant species were taken one time per month from January to December 2018. Three soil pits were made in three plots, and soil samples along 100 cm depth were taken on the same days of collecting plant samples for studying fied capacity, water content and water amount. The DDF was divided into three stands based on the most dominant tree species; Shorea obtusa, Dipterocarpus tuberculatus, and Dipterocarpus obtusifolius. The forest was composed of 86 species with biomass at 101.62 Mg/ha and contained an average water amount of 88.01 m3/ha. The water amount in biomass varied with sampling times from 58.74 to 111.83 m3/ha. The average MWHC of 100 cm soil was estimated to be 5,113.74 m3/ha. The water amount in soil also varied with sampling times from 3,651.50 to 4,481.06 m3/ha. As a result, the total water amount in plant biomass and soil (ecosystem) of the DDF varied in a range from 3,735.0 to 4,558.67 m3/ha. The pine contributed to 30.87 m3/ha (35.07% of the total) and could increase by 64.92% the water storage potential of the forest, and thus these results support the concept of pine enrichment planting in the poor DDF.
